How Is Promise All Different From Promise Allsettled Quiz Tl;dr promise.all() and promise.allsettled() are both methods for handling multiple promises in javascript, but they behave differently. promise.all() waits for all promises to resolve and fails fast if any promise rejects, returning a single rejected promise. promise.allsettled(), on the other hand, waits for all promises to settle (either resolve or reject) and returns an array of objects. Promise.allsettled will never reject it will resolve once all promises in the array have either rejected or resolved. their resolve values are different as well. promise.all will resolve to an array of each of the values that the promises resolve to eg [promise.resolve(1), promise.resolve(2)] will turn into [1, 2].
Promise Race Promise All Promise Allsettled Javascript Methods 47 Both promise.all () and promise.allsettled () methods are the methods of a promise object (which is further a javascript object used to handle all the asynchronous operations) that are used to handle multiple promises results simultaneously. Better handling of rejections using promise.allsettled () when it comes to executing several promises concurrently and waiting for them all to finish before using their resolved values elsewhere in your code, promise.all() is really useful. Difference between promise.all () and promise.allsettled () we have uncovered the difference of these two already with the coding approach; lets further theoretically discuss these the promise.all and promise.allsettled methods are both used to work with multiple promises, but they have different behaviors when it comes to handling resolved and rejected promises. here are the key differences. In simpler terms, promise.all() requires all promises to succeed — if even one fails, everything is considered a failure. in contrast, promise.allsettled() works more like a report: it tells you which promises succeeded and which failed, and still gives you the full picture.

Before comparing promise.all and promise.allsettled, let’s briefly understand how javascript handles asynchronous operations: javascript’s event loop: javascript uses an event driven model where tasks are executed in a single threaded event loop. promises allow non blocking execution by deferring certain tasks to the microtask queue. Learn the differences between promise.all and promise.allsettled in javascript. this post will show you the differences with example programs.
