as a software developer, as an experienced developer and teacher, let me tell you that GPT chat is a game changer. . you don't want to miss don't take my word for it just watch this video and see for

your

self my name is mosh hamadani and I'm very excited to bring you this

tutorial

on GPT chat. I have helped millions. of people learn to code and become professional software engineers through this channel and my online school codewithmash.com.

If you're new here, be sure to subscribe so you don't miss a video. So what exactly is GPT chat and how does it work? jpt chat is a cutting-edge artificial intelligence tool created by Open AI was launched in November 2022 and gained 1 million users in just 5 days, in comparison, it took Netflix three and a half years and Instagram two and a half months to get the same number of users. an advanced language model that can understand and generate text, you can use it to create content for your website, write articles, emails, tweets, cover letters, etc., you can also use it to generate code in several different programming languages, such as Python, JavaScript, HTML, CSS and much more, you can use it to generate dummy data, write unit tests, translate text or code from one language to another, you can use it to explain the code, for example, if there is a code snippet that you don't understand, you can ask it and I will explain it to you like a patient teacher, but I have to be honest, sometimes it explains too much.

GPT Chat can also help you learn and remember things faster, for example you can give it some text and have it ask you a bunch of questions. Prepare for job interviews, you can improve your resume, write a cover letter for yourself and also interview yourself like an interviewer. Now, do you think GPT chat will accept your work? Let me know in the comments below, the reality is if you like it. Whether or not GPT chat is here to stay in this tutorial. I'll show you how to use it to be more creative and get things done much faster.

I will show you several examples of different programming languages, both for beginners and experienced

developers

, but before we delve into that, let's take a moment and understand how gbt chat works. GPT chat uses a type of artificial intelligence called a language model. A language model is a type of software designed to understand and generate human language. By observing a large amount of text data and learning the patterns and rules of a language, for example, if the language model is trained with many English texts, it will learn about the grammar and structure of English, as well as the meanings of words and how they are used in different contexts once the language model has learned about a language it can then be used to generate text in that language now GPT chat provides different language models for different purposes gpt3 models that are designed to understand and generate natural language such as English and codecs that are specifically trained to understand and generate code.

These models are trained on billions of lines of code publicly available on GitHub. They are mainly capable in Python, but are also quite good in many other languages ​​such as HTML. CSS says JavaScript. type ruby ​​sql and more now before looking at specific examples remember to trigger GPT as any tool has limitations it can sometimes generate incorrect, harmful or biased information so don't take what I tell you as a silver bullet, don't use to learn to code because the code that is generated is not guaranteed to be correct, it may be functional but it may not be the best way to code, so in a nutshell,

chatgpt

is a powerful tool that can help you be more creative and efficient, but it is not a substitute. for human experience and judgment, so that's the theoretical part.

Now let's go ahead and see GPT chat in action, so head over to chat.openai.com. If you don't have an account, sign up, it only takes a minute once you're logged in. You will see the main screen with an input box to talk and chat GPT. There is also a Chrome extension and desktop app available if you don't want to use the web interface. I'll put the links below this video. Now let's get to the fun part. In the future, I will show you various use cases for different programming languages. We'll start with some general-purpose questions that apply to anyone, regardless of the programming languages ​​and tools they use.

You'll see how I can use GPT chat to learn new things write shell scripts get commands start a business write legal documents etc. Once we cover the basics, we'll dive into specific examples for database and back-end development. I'll show you examples. using HTML CSS JavaScript typescript python SQL and more now here is my first question what are the three best books to learn Java, as you can see GPT chat has given us a very complete and detailed answer now here we can ask more detailed questions, for example we can ask questions about the first book so we can ask what the key takea

ways

from Java are, okay, another complete answer.

You can see that this book teaches you about object-oriented programming, Java fundamentals, threading and concurrency, GUI programming, etc. We can also ask more general questions, such as how can I become a front-end developer. Now GPT chat says that to become a front-end developer you need to know the basics of HTML, CSS and JavaScript, you need to practice building websites and then you should do it. learn a front-end framework like react angular View etc., you should also know version control systems like git GitHub and Swap. This is pretty much the same answer you'll find on every website that gives you a roadmap to becoming a front-end. developer now let's look at more specific examples, we can ask

chatgpt

to write a shell command for us, for example we can say write a bash command to find the name of all the JPEG files in the directory and write them all to a text file .

I love this answer, so if you are not good with Linux commands, you can easily find the final statement that you should use to solve that problem, but the nice thing about chatgpt is that it also explains how this command works line by line, piece by part. We can also have GPT git network chat commands for us, for example we can ask how do I know how many lines of code I have committed to a Git repository. We can also use GPT chat to be creative, for example, let's say you want to start a business, you can have GPT chat generate app or website names for you, for example, we can say I want to create an online shopping app revolutionary, give me some good app names, so chatgpt suggests names like store, swift cart stream, etc., I think this list is pretty good now, these are just some example messages, you don't need to use exactly the same wording to speak by GPT chat, you can ask any question you want in your own way now, if you have used this tool before, please let us know.

In the comments below, the interesting questions you have asked so that we can all learn and inspire each other. We can also ask the GPT chat to write contracts for us. Here is an example. I want to hire a graphic designer to design a website. We have agreed that she will do it. Deliver the first draft in two weeks and offer three iterations for free. any subsequent iterations will be charged at fifty dollars an hour. write a contract for us, so the more details we give to the GPT chat, the better response we will get. Look, this is a pretty good contract to begin with, of course, you don't want to take it as is and use it in the real world without first running it through a real lawyer, which is why I told you before that CPT chat is not a replacement for humans at least none at the moment it's just a way to increase your

productivity

and get things done in less time now if you are applying for a job there are several

ways

GPT can help you for example you can have it write a resume for you listen to me, You can say that I have three years of experience coding in HTML CSS and JavaScript, write a resume for me, of course, we can give you more details, we can explain our level of education, our previous projects, etc., but look what. we get with this simple message, okay, take a look, so chat GPT created a basic layout that includes our name, address, phone number, email, an objective summary of technical skills and has already listed all the related web technologies , so we have HTML CSS JavaScript jQuery bootstrap.

He didn't mention any of this, but assumed that we have these abilities. It also included a section on professional experience which includes previous projects as well as educational certifications etc., again a great starting point. Now let's say you are requesting a front. -end the developer role, you can ask chatgpt to write you a cover letter that you can email to that company so that we can apply for a front-end and engineer position in some company, write me a cover letter, okay, take a look, we have a full cover letter beautifully written in perfect English how good is that now let me show you another fun one you can have chat GPT ask you interview questions we can say act like a technical interviewer and ask me five questions about JavaScript take a look , so here we have five questions that are often asked in technical interviews.

Now let's say you don't know the answer to the first question. You can ask a follow-up question. So the beauty of GPT chat is that it remembers everything you've told it. In this conversation thread, here we can say what is the answer to the first question again. We get a very complete detailed answer. You can also ask GPT chat to help you write emails, for example, we can say write an email to my boss asking for a raise. I have worked in this company for two years and successfully delivered several projects on time. Seriously, if I wanted to write this myself, it would take me 10-15 minutes, if not more.

I got the answer in just two seconds. Okay, now let's see. Some examples involving code, we'll start with using Python to write a command line tool. We can say write a Python function to generate a random password. As you can see, we get a beautifully highlighted code snippet with an explanation of how it works now. If there is a part of this code that you don't understand, you can always ask follow-up questions, for example, we can ask what this expression does in this code, then we can ask what does 4 in range I of length 2 mean in this code. a really very useful look couldn't be better now we can also ask computer science questions like what is the time complexity of this function now if you are not familiar with this concept time complexity is a way of explaining how large inputs affect the performance of an algorithm is really beyond the scope of this tutorial.

I've covered it in detail in my data structures course in case you're interested, so let's see what we get. GPT says that the time complexity of this function is linear, now let's take this to the next level, we can ask chatgpt to write unit tests for this function, so write unit tests for this function seriously, how good is this? If I wanted to write all of these unit tests by hand, it would probably take me 20-30 minutes, otherwise Of course, we should always use our own judgment to make sure the tests are correct, but I think this code is a great point of reference. departure and really saves us a lot of time.

We can also ask the GPT chat for ideas to improve our code. For example, here at w3schools.com we have this Python code snippet where we use a for loop to iterate over a list of fruits, if the fruit has content we add it to a new list. I'm going to copy this code and hit the GPT chat to see how we can improve this code, so see how I can improve this code now here we need to hold down the shift key and then press Enter to go to the next line, now we paste our code and then we press Enter to submit the question, okay look at a lot of details, absolutely amazing, one thing I love here is that chat apt suggests using a list comprehension, which is a single line to implement the same logic, of course there are more ways to improve this code.

We are not going to go into details here, we can also ask chat jpt to convert our code from one language to another, for example, we can say convert this code from Python to foreign JavaScript. In just a few seconds, our code was converted to JavaScript andbelow we have all the details about how this code works, we can also use CPT chat to generate dummy data, for example we can say generate dummy data for a table called customers, each customer must have an id, first name, last name and city, now In this case, the GPT chat provided we use a Python script to generate dummy data, but what if we want the real data, not a Python script?

We can say that I don't need a Python script, just give me the data, so now we get a list of 10 people represented using Json format. Now we can take this to the next level and say create a Python class to store these objects. Looking externally, we get an example of a Python class called client along with how we can use this class to store a bunch of client objects inside the list absolutely. Beautiful now, if you are a front-end developer, you can ask chat jpt to generate some HTML markup for you and this is where the examples become more and more interesting, for example, we can say write the HTML and CSS code to display a foreign card. a look, we have the markup here, we have a div with the card class inside the div, we have an image, then we have the content of the card inside this div, we have the card title and the cart description, really very good, and just below we have everything.

The CSS we need to display a beautiful card, of course, we'll probably need to customize it, but again, this is a great starting point. Now we can stop here or we can customize it further, for example we can say add a button below the card content. What happened? Now we have a new markup just below the card description. We have a new div with the card action class and inside this div we have a beautiful button now we also have more styles for this button we have the flat styles as well as the styles for the hover effect now let's take this to the next level We can say when I hover the mouse over the card I want the card to slide up slightly, so load it if you suggest that we should use the floating sudo class and the Translate Y translation function to slide the card up beautifully.

I love it, it also suggests a workaround using Box Shadow, so it's pretty up to date. CSS features now let me show you something really interesting. We can ask the GPT chat to rewrite this code using Tailwind CSS. If you are not familiar with Tailwind, it is a CSS library that has gained a lot of popularity lately, so here we can tell you: can you rewrite it? this code uses foreign Tailwind CSS, there you have it, now we have the same markup but with the utility classes that come with Tailwind CSS, so we no longer have to create CSS classes.

Now here we can be more creative and see what other UI libraries are supported. next we can throw some JavaScript into the mix and make it interactive so we can say that when I click the submit an HTTP request button to trim the API, trim the foreign products, let's see the generated code for the GPT chat to suggest using the fetch API which is supported by pretty much most modern browsers, but I personally don't like using the fetch API, so I'm going to customize this even further and say that instead of the fetch API, use the axis, which is a library for sending HTTP requests.

Now take a look. Alright, now we have instructions for installing axios using npm or thread, as well as a modified example using axis beautiful. We can also ask the GPT chat to help us with compile time or runtime errors. Here's an example, let's say it's part of writing JavaScript. code, we get an error saying uncut type error cannot read property, say undefined slash. Anyone who has written a bit of JavaScript code has probably encountered this error, so we can copy and paste the error message here now. GPT Chat explains exactly what this error is. what it is and how we can potentially solve it, so in the future I think a lot of people will start using GPT chat instead of Google.

Now we can also launch react here and make the example more interesting so we can say create a react component to display a card, okay let's see what's going on here, up here we have an example of a function component to display a card . Now, personally, I don't like having a parameter called props. It would be better to destructure this parameter and take individual properties like the title. description and so on, so if you're not familiar with this concept, don't worry, keep watching. We're not going to do a lot of fancy JavaScript stuff in this video, this is just to open your eyes to the possibilities, so let's take this to the next level and say this props parameter structure, so the beautiful thing about GPT chat is that it remembers our conversations, so let's move on.

We have a new implementation of the card component with the props parameter destructured. Now let's move on. and look at some examples involving backend development, for example we can ask chat jpt to create an API for us with node and express, so here we can say I need an API created with express.js to return the list of products of each product. it should have attributes like id title description price and image url thanks ok look at this implementation in this implementation we have a products area stored in memory and we have an API endpoint exposed at this url I don't want to have a products area in the memory I want this product to be stored in a mongodb database, so here we can say modify the code and retrieve the products from mongodb or MySQL or postgres, any database.

Now we get a new implementation where the products are retrieved from a mongodb database using the Mongoose library here now it is in this implementation the type of these parameters is not clear because this code is simply JavaScript now we can improve this implementation and use typescript, for what we can say using typescript in this code now we have a new implementation of the same web server implemented using typescript. Now let's say you are a Python developer and you don't want to use JavaScript, so here we can say you build this API using Python and a quick API, which is another library for building APIs using Python.

Alright, now we have a new implementation, but in this implementation our products are stored in memory again, we can talk to GPT via chat and customize this further. Now let's look at some examples involving databases. This one is pretty interesting, so I'll go. say write a SQL query to generate a table called products with four columns note that I am not specifying the column names and types here I am just saying I want a products table with four columns see what happens now look chat GPT is smart It's enough know that very often products have attributes such as ID, title, description and price.

If this is not what you want, you can always specify the name and type of each column, for example we can say write a SQL query to generate a table called products with these. columns now here we press shift and enter to go to the next line and in each line we can list a column, we can say ID of type integer title of type string category of type integer unit price of type float and image URL of type string and not necessarily you have to put a type in parentheses, you can type a colon and immediately after that we can specify the type so that the GPT chat doesn't have a particular syntax that it has to follow because it can understand human language right now. in products table we have columns like ID title category unit price and so on we can also use GPT chat to write queries to retrieve or update data, for example here we can say write a query to retrieve top five customers in Manhattan, please note Note that We currently don't have a table called customers, so we just ask chatgpt to write a query to retrieve the top five customers in Manhattan.

Take a good look at this example. Chatgpt has assumed that we have a table called customers with the ID name of these columns. address and city, if our customer table has a different schema, we need to specify it in advance, so we specify the name and type of each column, then ask the GPT chat to write a query to retrieve the top five customers. Now look at this query in In this query we simply select clients that are located in Manhattan, so in this query the clients are sorted by their ID in descending order and the top five are returned.

This is not what we really want, what we want are top spending customers. the most, so we need to be more specific with our message, so we need to tell the chat CPT to join the order table to know how much each customer has spent and then it should select the top 5 customers who have spent the most . We can say check this query and join the customers table with the orders table to know how much each customer has spent, then choose the top five who have spent the most and again here we can also specify the order table schema, so go ahead , okay, look now GPT chat assumes that we have two tables of customers with these columns and orders with these other columns and, according to this schema, it has revised our query to retrieve the top five customers who have spent the most, so that's it, guys.

There are endless ways to get creative and use GPT chat. I hope you found this video useful, if you enjoyed it please like and subscribe to see more videos like this. Also let me know in the comments section what interesting questions you've asked the GPT chat. I'd love to hear from you, so thanks for watching and I'll see you in the next video.
