🧵 JavaScript Promise methods 🧵
In this thread we will learn how to compile the results from the multiple async operations using the following methods: ⬇️
▶️ Promise.all()
▶️ Promise.race()
▶️ Promise.any()
▶️ Promise.allSettled()
▶️ Promise.all()
It takes the array of the promises and gives the following output 👇
- If all promises are resolved then output is the array of resolved promises.
- If even one of the promises is rejected it gives the output of the first rejected promise.
▶️ Promise.race()
It takes an array of promises and returns the promise's value, depending on which one is resolved or rejected first.
▶️ Promise.any()
It returns the value of the promise that is resolved first even if there is some promise which is rejected. It will return the value of the first resolved promise.
▶️ Promise.allSettled()
It returns a new promise that resolves when every input promise has settled with an array of objects that describes the result of each promise in the iterable object.
