[0:00]Hello everyone, welcome back to the Search Creators YouTube channel. Okay, so the subject code is BIS 601, and the subject name is Full Stack Development.
[0:10]Okay, so in the last video, we discussed the important question paper or passing package questions for module 5. Now, we will look at module 4.
[0:22]Before that, many people are still confused about how to download this important question paper, where to find it, and what it is. We are getting a lot of comments and calls.
[0:34]Okay, I will tell you the solution. Just go to Google or whatever browser you have and type BIS 601. Just okay.
[0:46]Then press enter. You will see the first link. On mobile, it will appear small, but the first link will look like this: Full Stack Development. Click on it.
[0:57]Okay, so this page will open. On mobile, it will be a bit condensed. If there are any advertisements, click the down arrow, and it will go down.
[1:05]Then scroll down, and you will see "I Understand." Click on it. Okay, so the complete page will open.
[1:14]Here, scroll all the way down. You will see a QR code. Scan this QR code, and for each module, it will cost Rs 5.49. Okay, so look, if you scroll down, you will see everything.
[1:26]But if you want all five modules at once, you can use this QR code. Each module costs Rs 5.49. So if you want five modules, it will be Rs 27.45.
[1:38]After paying that amount, send a screenshot of your payment confirmation to the WhatsApp number you see here. Our team will verify your payment and send you the download link for the notes within five minutes.
[1:48]That's what's written here in the important notification. Please read it carefully once, okay? You won't have that much time. Read this, and you will understand. Okay, I have explained it simply here.
[2:00]Now let's look at the questions. So, for module 4, what kind of questions can they ask? First, module 4's name is React State. I hope you know what React is. I think you might have studied it in class or generally know about it. It's better.
[2:16]Okay, so let me tell you in simple words what React means. It is a programming language. Okay, so it's a JavaScript programming language. Okay, so in this, what kind of questions can they ask?
[2:29]First, the first question they might ask is: Explain the concept of state in React. How is it initialized and updated? Give examples. Wherever they ask for examples, you have to write the code.
[2:47]So, they might ask a question like this. I have prepared 10 questions here. They can ask any of these 10 questions. The Issue Tracker is present in every module. If you read that once, you can answer any question about the Issue Tracker in every module.
[3:00]That is the second question: What is lifting state up in React? Explain with the Issue Tracker example. Okay, they might ask a question like this.
[3:09]Next, the third question: Discuss the React component lifecycle with respect to asynchronous state updates. For the React component lifecycle, you must draw a diagram. Okay, so you have to draw a diagram for this.
[3:23]If you refer to our notes, you will get the answers to all these questions. We have released important question papers or passing packages, and all those questions are what VTU might ask. Okay, so only in our website's notes will you find the answers to all these questions.
[3:45]You won't find them anywhere else, like in textbooks or online. You won't even find the correct answers if you search on ChatGPT. It will give you answers that you will understand, but we haven't prepared these notes or questions using ChatGPT answers.
[4:01]We have created these questions based on the notes we have created. Okay, so you will only find these questions in our notes. You won't find them anywhere else.
[4:08]Next, the fourth question: Describe the process of adding a new issue using user interaction (form and button) in the Issue Tracker. See, I told you that any question on the Issue Tracker, if you read it once, you can answer any question on the Issue Tracker.
[4:26]So, how to create a new issue, how to add an issue, how to perform CRUD operations, they might ask here. Read this once, okay? Next, differentiate between state and props in React. When should you use each? Okay, for this type of question, where it asks to differentiate, understand that you need to draw a table.
[4:51]You have to write it point-wise. For any question, write it point-wise, include a diagram, and a simple coding example. This is a must. Next, the sixth question: What are stateless components in React? Explain their benefits with code examples. They might ask this, they might ask about stateless components.
[5:08]Next, what is GraphQL? Compare it with REST. Explain over-fetching, under-fetching, and how GraphQL resolves these issues. Maybe this question will also be asked in the exam. Okay, so for this, what you have to do is first, you have to write what GraphQL is.
[5:35]Then, when it says compare, you have to write the difference between REST and GraphQL in a table. You have to write it in a table like this.
[5:49]Next, what is GraphQL? How does it resolve issues? You have to write that. You have to write it point-wise. Okay, next, the eighth question: They might ask this question as well. So, explain how to define and use a custom scalar type (GraphQLDate) in GraphQL.
[6:11]All these remaining two questions, from seven to ten, are about GraphQL. Next, the ninth question: Describe the structure of a GraphQL mutation to add a new issue using query variables. They might ask this too. It's possible.
[6:33]Okay, so the 10th question: Explain input validation in GraphQL using enums and programmatic validations with resolver functions. They might ask this too.
[6:49]So, what is very, very important among these 10 questions I have prepared? They might ask four questions from these. Maximum four questions.
[6:57]These are expected questions. We are not giving you any hope that these will be given. We are just expecting that these kinds of questions can be asked based on this concept. Just be ready with this concept. Okay, so the answers to all these questions are only available in our notes on our website.
[7:13]And in-depth, how to write point-wise. If you want to write more advanced, you can also find the answers in the textbook provided by VTU. You won't find them on any other website. Okay, so I hope you understood about module 4's important questions and how the passing package is prepared.
[7:33]If you have any doubts, my number is given in the description box below, and my WhatsApp number is also given. If you want to download the important question paper, you have to pay Rs 5.49. Only after paying will our team send you this paper.
[7:50]Okay, so if you have any doubts, please call me. I will answer directly. Okay, thank you for watching this video.
