Q2. Async and await difference
Ans. 
Async and await are keywords in JavaScript used for handling asynchronous operations.
• Async is used to define a function as asynchronous, allowing it to use the await keyword.

• Await is used to pause the execution of an async function until a Promise is settled.

• Async functions always return a Promise, which resolves with the value returned by the function.

• Using async/await makes asynchronous code easier to read and write
