Defining an Async Function
An async function is declared using the async keyword before the function declaration. This signifies that the function will contain asynchronous operations and will return a Promise implicitly.
Inside an async function, you can use the await keyword before a Promise to pause the execution of the function until the Promise resolves or rejects. This helps avoid callback hell and promotes more linear and readable code.
You can use a try/catch block to handle errors that might occur during asynchronous operations inside an async function.
Awaiting Multiple Promises Concurrently
Async/await allows you to execute multiple asynchronous operations concurrently and wait for all of them to complete using Promise.all().
Using Async/Await with Other Promise-Based APIs
Async/await can be combined with various other Promise-based APIs, like timers, FileReader, and more.
