Async Await Vs Promises Which Should I Use In this tutorial i explain what javascript promises are, why we need them, and how to use them, catch errors properly and then convert the same code to use async and await. Put "async" in front of a function. and we can use "await" to wait for promises that take their time in getting back to us. you can only use await inside an async function. without async await, line 3 would console.log 'undefined', as the fetch request would still be processing.

Async Await Vs Promises Is Async Await A Good Idea Javascript provides three main ways to manage asynchronous tasks: callbacks: the traditional approach using functions passed as arguments. promises: a better alternative that improves readability and avoids callback nesting. async await: a modern and cleaner syntax that makes asynchronous code look synchronous.
