Sorry. Uh, hello. My name is Nickel. I've worked in the Pro for 2 years as a post tech web developer. And as of my, uh, education career, I've done my BTech in computer science and engineering. It's from IMT University, May, and I have passed in year 2022 with 80% marks.

Hi. My name is Nikhil. I have, uh, 2 years of experience in full stack development. I have done my engineering in computer science and engineering from IIM University major, and I have secured 80% marks. And after that, passing out in 2022, I have joined with the host that we have developed. Thank you.

I guess we can use, uh, array which should be initialized with cons. Like, it should be a consquared equal to n n n n t a. Yes. And we are returning a square of every number. So yes.

React app performance has degraded significantly as data volume grew. What step I can take you in? We have the different tools on the profile to identify and solve this. So we can proceed with, like, uh, we can, uh, like, we can optimize data fetching, uh, like, implement pagination, use instant scrolling, optimize API calls, uh, lizard, server side rendering. And, uh, we can also use, uh, comp we can optimize component rendering. We can optimize state management using the state management every week. Uh, we can use selector. We can optimize the data structure of the code. There are many more, like, uh, image optimization, DOM manipulation. Uh, this we can use these strategies.

So according to question, uh, when building a dashboard that needs to display a large dataset, basically, it is crucial to optimize the rendering rendering to provide seamless user experience. So we can follow the following, uh, strategies such as pagination and in flight scrolling, data virtualization, optimize component and key, efficient data structure. We can also optimize DOM manipulation, uh, use, uh, service side and key. We can also optimize data fetching, optimize images. And, uh, yes, you can use this.

So please give me a couple minutes. Can you oh, in the potential issues memorized? Okay. So, uh, this is a common state management pattern, but, uh, but it has some potential drawbacks, which is, like, insufficient state updates, like, directly mutating the state of the 2 in this set state, um, set state callback and lead to the performance issue, especially when, uh, dealing with complex state structures and also race conditions. If multiple state, uh, updates happen quickly, then then they can potentially override each other. So and also difficulty in testing the impenitive nature. Set state calls can make testing the phone more challenging.

Explain method to efficiently execute complex query in MongoDB that needs to read and write data and know this activity. A method to efficiently execute complex query in MongoDB that needs to read and write data in Node. Js application. So So, basically, uh, we can use asynchronous operations for efficient reading. Uh, we will use the FS module, uh, buffering, caching, and file statements for the speech and writing.

So, uh, the essential method for properly and counting components that involves ongoing replay is called a component fee amount an amount. This live checking method is called immediately before a component is unmounted from the, uh, dock. This ideal place to, uh, clean up any sources of side effects that were created during the company's life time.
