How To Wait For 2 Or More Promises To Resolve In Javascript

Wait For All Promises To Resolve In Javascript Waiting for multiple promises in javascript involves using promise.all () or promise.allsettled () methods. these methods accept an array of promises as input. promise.all () waits for all promises to either resolve or reject, providing a single promise that resolves with an array of results or rejects with the first rejection. I would add that if any of these promises rejects, promise.all will immediately reject (whether or not the rest have finished) and the then will be skipped. if you need to run dosomething() whether they succeed or they fail, you need to catch each of then individually to return a promise.resolve().

Learn how to use javascript's promise.all method to await multiple async operations, as well as how to write a custom implementation of promise.all.
