Introduction
Async code is a code that does not execute immediately. It executes after some time. Async code is used to perform long-running tasks without blocking the main thread.
Callback Functions
A callback is a function passed as an argument to another function. This technique allows a function to call another function.
Promises
A promise is an object that represents the result of an asynchronous operation. It is used to handle asynchronous operations in a better way. It is a replacement for callbacks and events.
Async Await
Async Await is a new way to write asynchronous code in JavaScript. It is a syntactic sugar over promises. It makes asynchronous code look like synchronous code.
