[00:00:00]  I'm audible properly?
[00:00:02]  Yes.
[00:00:03]  Okay, great then.
[00:00:05]  So quickly begin with your introduction first.
[00:00:09]  Yeah, myself Chetan Purnagopal and I'm from Barangal.
[00:00:12]  I've completed my graduation in the stream of Compressance and Engineering in the year 2024.
[00:00:17]  After my graduation, I took training on the Manstack through the next year, where I developed my skills in the Node.js, Express.js, React.js, MongoDB, SQL Lite.
[00:00:28]  Using these technologies, I've worked on different projects like front-end projects and full-stack projects as well.
[00:00:36]  Apart from these technologies, I do have skills in Python and along with its libraries, NumPy and Pandas, which is great working with the AIML and data.
[00:00:48]  And recently I've attended a workshop where I gained knowledge on the prompt engineering techniques and LLM models, how to use LLM models to
[00:00:59]  leverage the code quality and improve the code efficiency.
[00:01:03]  So this is all about me.
[00:01:05]  Thank you for giving time to introduce myself.
[00:01:10]  Okay, that's great to know about you, Chetan.
[00:01:13]  So apart from one stack, you know Python as well?
[00:01:19]  Yeah, Python as well.
[00:01:20]  Okay, that's great.
[00:01:22]  So please share your screen.
[00:01:26]  And create a one blank react project.
[00:01:45]  Can you able to see my screen?
[00:01:47]  Yes.
[00:01:50]  What I need to do?
[00:01:52]  Create a blank React project.
[00:02:00]  VS code do you have?
[00:02:01]  Yeah, yeah.
[00:02:03]  Open that.
[00:02:58]  So, to develop React projects, we need some dependencies.
[00:03:02]  We need to run some commands initially.
[00:03:05]  Let me set up.
[00:03:11]  Create one blank project.
[00:05:08]  Do you have a pilot enabled in your system?
[00:05:14]  Good morning.
[00:05:24]  Hello.
[00:05:25]  Yeah, yeah.
[00:05:27]  Yes, sir.
[00:05:28]  You have a pilot enabled in your system?
[00:05:30]  Yes, yes.
[00:05:31]  Can you please disable it or uninstall it?
[00:05:44]  I don't have explicitly installed that co-pilot app like disabled it.
[00:05:52]  I have disabled by typing anything.
[00:05:55]  Here it will appear initially it will appear here i disabled it you have disabled it yeah okay remove that uh or enter code this const count etc whatever is it uh uh
[00:06:11]  this thing above above above line number seven remove that
[00:06:22]  Now I'll share you one API endpoint.
[00:06:26]  Okay.
[00:06:28]  Just.
[00:06:30]  Just fetch the results from this API and show me on the browser the name of candidate, the name of the user and his email id.
[00:08:05]  is not responding then you can use what is that explorer
[00:08:12]  Use Explorer if you want.
[00:08:15]  Or any other browser.
[00:10:07]  That was a little bit of a surprise.
[00:12:17]  The co-pilot is still working.
[00:12:24]  So, I never used the co-pilot in my...
[00:12:28]  Then how it is?
[00:12:31]  Giving you the right solutions.
[00:12:37]  Go to the extensions.
[00:12:40]  Hello.
[00:12:41]  Click on extensions.
[00:12:42]  Click on extensions.
[00:12:47]  Yeah.
[00:12:49]  Search Copilot.
[00:13:03]  Polycon, right?
[00:13:04]  It's a good thing, you know.
[00:13:11]  Disable it and install it.
[00:13:16]  above on also uh it automatically got now it's fine now go and vote
[00:13:31]  Now start writing the book.
[00:13:43]  And I don't have much time, so please...
[00:13:48]  Actually, my network is low.
[00:13:51]  Sorry?
[00:13:53]  My network is pretty low.
[00:13:56]  Still, I think...
[00:13:58]  Where it is coming?
[00:13:59]  The profile is working.
[00:14:02]  Restart your waste code once.
[00:14:04]  Close it and restart it again.
[00:15:35]  What happened?
[00:15:35]  It got stuck?
[00:15:40]  Hello.
[00:15:56]  Hello, Sweden.
[00:16:01]  Hello, Sam.
[00:16:01]  What's up?
[00:16:03]  Hello?
[00:16:07]  Lias, what's happening?
[00:16:08]  Your screen was greased for a while.
[00:16:16]  I think there is some network issue from remote area.
[00:16:22]  Okay, continue then.
[00:17:43]  I didn't see that.
[00:19:19]  What is the concept of virtual domain react?
[00:19:24]  Sir?
[00:19:25]  Hello?
[00:19:26]  What is the concept of virtual domain reactor?
[00:19:32]  Virtual domain, which like it will
[00:19:38]  And.
[00:19:41]  Dom is a tree structure or small down which will store the
[00:19:50]  like instead of rendering an entire component let me take an example if when I run an application or run a web application instead of
[00:20:00]  entire application, it will only load a specific component.
[00:20:07]  Whenever a user triggers the state variable or if the props are changed, it will trigger only a specific component.
[00:20:20]  Like instead of rendering every component in an application, it will render only that specific component.
[00:20:29]  So it can improve the performance of a React application.
[00:20:35]  Okay, why we use use effect?
[00:20:39]  Use effect is used to work with the side effects like asynchronous functions.
[00:20:51]  As you can see, fetching the data.
[00:20:55]  Fitting the data from an API and like login authentication, generating the JWT token.
[00:21:07]  For these kind of things, we use user effect.
[00:21:11]  Okay.
[00:21:12]  So if we are trying to fetch data or
[00:21:16]  access any API without using the effect, then what will be the issue?
[00:21:21]  Without using?
[00:21:24]  Without using any use effect.
[00:21:26]  If I'm making an API request, then we
[00:21:31]  through any error?
[00:21:34]  Like it will, yeah, it will not cause any error, but it will stop at that line.
[00:21:45]  What asynchronous functions do, it will allow other processes to complete.
[00:21:55]  These fetching method will take some time compared to the other normal print statement or consult statements will take some time.
[00:22:04]  Do not erase any error, but it will decrease the speed of an application loading speed of application.
[00:22:14]  Okay.
[00:22:15]  Yeah.
[00:22:15]  Fine.
[00:22:16]  So why are the keywords async and await used together?
[00:22:23]  Await like async asynchronous async keyword is used to tell a function is an asynchronous function and await keyword is used to a specific like in front of this fetch method we use the await
[00:22:37]  we are letting the browser that it will take some time so in the meantime we can you can go through other processes which will take some less time
[00:22:49]  So it will allow backend.
[00:22:53]  These keyword allow run this process in the backend.
[00:22:58]  Meanwhile, other process.
[00:23:00]  are executed.
[00:23:02]  Okay, we will not use this await keyword then what will happen?
[00:23:08]  Like it will, as I said, it will stay on that line.
[00:23:14]  It will like a synchronous function.
[00:23:17]  It will, as JavaScript is a synchronous language, it will execute every code line by line.
[00:23:26]  Even after executing a specific line, it will move to the next line.
[00:23:31]  If you don't use a specific keyword like await, it will stay on that line and it will take some long time.
[00:23:39]  Which may crash the application in some times as well.
[00:23:43]  If we are not using that await keyword, then it will crash the application.
[00:23:49]  Yeah, like not that way.
[00:23:51]  Like it will take some long time to load the application.
[00:23:57]  Okay.
[00:23:59]  Fine.
[00:24:00]  So why we use use state?
[00:24:03]  Use state.
[00:24:03]  Use state is used.
[00:24:05]  Actually, a state is a mutable changing object.
[00:24:12]  Whenever the user requests changes, these state variables changes like the state we can
[00:24:21]  Using this use state, we can create some state variables like username.
[00:24:30]  user credentials, whatever it might be.
[00:24:33]  The input changing over time, we put in these state variables.
[00:24:42]  Use state contains a variable followed by the callback function.
[00:24:49]  Here I am just using a simple variable instead of use state.
[00:24:53]  Then what will be the issue?
[00:24:56]  Like I don't understand.
[00:24:57]  Can you repeat?
[00:24:59]  Suppose I don't want to use use state in react.
[00:25:02]  I just want a simple variable to store my accounts and every data in simple variable.
[00:25:09]  Then what will be the issue that it will create?
[00:25:13]  Like it will render whole application.
[00:25:21]  Like instead of rendering a specific component or a specific section, it will render a whole application.
[00:25:33]  Okay.
[00:25:34]  What are REST APIs?
[00:25:36]  REST API is not a technology or concept.
[00:25:41]  It is an app text style of defining the APIs.
[00:25:46]  Like API is nothing but a bridge communication between the two softwares, like client and server.
[00:25:56]  Through this REST API, it will allow us
[00:26:00]  some HTTP methods directly, which like software communicate through like
[00:26:07]  some HTTP methods like get post put delete, like getting the fixing the data, updating the data, inserting the data, deleting the data.
[00:26:17]  So the
[00:26:21]  STTP like in the REST API, the software will communicate to the API URLs over the internet using these HTTP methods.
[00:26:35]  Yeah.
[00:26:35]  Okay.
[00:26:36]  Okay.
[00:26:37]  Understood.
[00:26:38]  Chetan, it was great interacting with you.
[00:26:40]  Do you have any questions for me?
[00:26:43]  Like, can you tell more about the company?
[00:26:47]  Because when I'm searching on the internet, it's not giving the proper answer.
[00:26:53]  Like, some websites are saying it's a cryptocurrency company, a blockchain technology company.
[00:27:01]  Can you explain in details what actually it is?
[00:27:07]  So we are an IT company.
[00:27:09]  Okay.
[00:27:09]  We build software, software as a product and as a service that we sell to our clients.
[00:27:16]  Okay.
[00:27:17]  And we use the blockchain and AI also.
[00:27:20]  Okay.
[00:27:22]  For building software platforms.
[00:27:25]  Okay.
[00:27:26]  Who is the clients of this company?
[00:27:29]  Like who is the...
[00:27:30]  As of now, what kind of major issue, like a big project you have worked with?
[00:27:41]  So we are working on a portal called highstar.io.
[00:27:44]  It's a background verification company.
[00:27:46]  And our clients are big, big companies.
[00:27:51]  Who are hiring a lot of candidates and who wants to run background verification check on their candidates.
[00:27:59]  Okay.
[00:28:01]  Thank you.
[00:28:01]  That's all about my end.
[00:28:04]  Okay.
[00:28:05]  Thank you, Chitran.
[00:28:06]  Thank you.
