why asynchronous code is important in JavaScript

Why asynchronous code is important in JavaScript?

Explained In detail as given below
  • Using Asynchronous code, we are able to execute multiple things/JavaScript call at the same-time without locking the DOM or main thread.
  • You can define a global variable for call-back method.
  • You can use call-back method because JavaScript is lexical scoped and can't define a variable in the call-back methods.
  • The response and data come from the parent's call-back method.
  • etc..

Thank you!
