The Promise.all() Method

Discover how the Promise.all() method resolves when all of the promises are resolved.

Handling multiple promises

Sometimes, we want to monitor the progress of multiple promises in order to determine the next action. JavaScript provides several methods that monitor multiple promises and respond to them in slightly different ways. These methods allow multiple promises to be executed in parallel and then responded to as a group rather than individually.

The Promise.all() method accepts a single argument, which is an iterable (such as an array) of promises to monitor, and returns a promise that is resolved only when every promise in the iterable is resolved.
