Hi Sofia ma'am, I want to say you something today from the bottom of my heart.
I was jobless for 1 whole year, But I decided to restart again, I started giving interviews and soon I realised that at first place I scared to sit and face the interview, but after multiple rescheduling I dare to face one interview and as decided I was rejected, I didn't even answer the simple question like diff between local storage, session and cookies...
But here comes God's plan I searched it on YouTube and found your video, ma'am maine 1 month main apka poora content 2 se 3 baar dekh lia...
I waited this day to comment that you are not just a Youtuber or a content creator, you are a HOPE
1 year career gap hone ke baad bhi I successfully cracked one of the world's biggest company.
To just say "Thank you" to you is disrespect, it is a very small word if I say it to you, so I would say as my mother learned me, you came in my life as a Lakshmi Ji. I will always be grateful for you 🙏.

useQuery is a hook from React Query that helps you fetch and manage data from a server in a simple way.

How it works:
1. Fetching data: useQuery automatically runs a function that fetches data (like from an API) when the component using it is loaded.

2. Tracks status: It handles and tracks the different states for you:
a. isLoading: While the data is being fetched, this is true.
b. error: If something goes wrong during fetching, it stores the error.
c. data: Once the data is fetched successfully, it stores the data here.

3. Caching: It automatically caches the data to avoid redundant network requests. If the same data is needed again, React Query can use the cached version.

4. Auto Refetching: It can automatically refetch the data when it becomes "stale, " or when the user interacts with the app (like changing pages).
