How does bluebird.all work?

bluebird.all is a method in the Bluebird promise library that takes an array of promises and returns a new promise that resolves with an array of the resolved values of each promise in the input array. When bluebird.all is called with an array of promises, it creates a new promise and returns it immediately. It then begins to iterate over the input array and waits for each promise to resolve or reject. If any of the promises reject, the promise returned by bluebird.all will reject with the same reason. Once all promises in the input array have resolved, the promise returned by bluebird.all will resolve with an array of the resolved values. The order of the resolved values in the output array corresponds to the order of the promises in the input array. It's important to note that if any of the promises in the input array are rejected, bluebird.all will immediately reject with the reason of the first promise that rejects, and any other promises that are still pending will be ignored. Here's an example of using bluebird.all to wait for multiple promises to resolve: javascript Copy code {{{{{{{ const Promise = require('bluebird'); const promise1 = Promise.resolve(1); const promise2 = Promise.resolve(2); const promise3 = new Promise((resolve, reject) => { setTimeout(() => { resolve(3); }, 1000); }); Promise.all([promise1, promise2, promise3]) .then((result) => { console.log(result); // [1, 2, 3] }) .catch((error) => { console.error(error); }); In this example, we create three promises: promise1 and promise2 are immediately resolved with values of 1 and 2, respectively, while promise3 is resolved after a delay of 1 second using a setTimeout call. We then call Promise.all with an array of these three promises, and attach a then callback to log the resolved array to the console. The output will be [1, 2, 3], indicating that all three promises have resolved successfully.
