Question:

What is asynchronous programming, and why is it important in JavaScript?

Shayan S.
Answer:

Synchronous programming means that the code is executed sequentially from top-to-bottom, blocking on long-running tasks such as network requests. Asynchronous programming starts with a request and the code keeps running without blocking for the result. When the response is ready, an interrupt is fired, which causes an event handler to be run, where the control flow continues. In this way, a single program thread can handle many concurrent operations.
