What Is Asynchronous Programming

Synchronous

The process and execute one task at a time.

Cons of Synchronous Programming:

• Delay of other tasks (e.g. make Network requests)
• Appearing responsive to the user

Asynchronous

Getting other work done while you wait for a test to finish is the basis of asynchronous programming.

Async code structure ≠ Sync.code structure

Asynchronous code is structured with callbacks (i.e. a function passed to another function as an argument and only runs after the parent function has finished executing).
