What do async and await do in JavaScript?
JavaScript async and await provide a way to express work that depends on promises. An async function returns a promise, and await pauses that function until the awaited result settles without blocking the whole page.

A cinema page might need a selected venue before it can show that venue’s screenings. The dependent work has a natural order, while other page activity can continue. Async and await describe that waiting relationship; they do not make a remote service respond faster.
Waiting for one result does not freeze every activity
Async and await provide a way to express work that depends on promises. Within an async function, a later operation can depend on an earlier result. That relationship does not mean the browser must stop responding to every other interaction while the result is pending.
Several pieces of information may also be independent. A profile image and a list of saved items can have different loading and failure states. Understanding those dependencies helps explain why one part of a page can be ready while another still has work to finish.
