A promise has three states:
When a promise is fulfilled or rejected, it is settled, and its state won't change after that. This behavior ensures consistency throughout the execution of your code.
Sometimes, you might need to execute multiple promises and wait for all of them to be resolved. This is where
Promise.all() comes in. But what does
Promise All do?
Promise.all() is a method that takes an array of promises and returns a new promise that resolves when all the promises in the array have been resolved or rejects if any of the promises are rejected.
Here's an example of using
In this example,
Promise.all() is used to aggregate the results of multiple promises. This is particularly useful when you have several asynchronous operations that are independent of each other, and you want to wait for them all to complete before proceeding.
