What is async await in javaScript

I define an async function by placing the async keyword before the function name. This tells JavaScript that the function will contain asynchronous operations.

Inside this function, I create a promise and assign it to a variable. To ensure the code waits for the promise to resolve or reject, I use the await keyword. By doing this, I tell JavaScript to pause execution until the promise has been settled (either resolved or rejected).

After the await keyword, I create a new promise using new Promise(). This creates a promise object that takes a callback function with two parameters: resolve and reject. These are used to handle the success or failure of the asynchronous operation:

If the operation is successful, I call resolve() and pass the result to fulfill the promise.

If something goes wrong, I call reject() and pass an error or reason for the failure, which will reject the promise.
