The traditional way to create a promise is using the ๐๐ซ๐จ๐ฆ๐ข๐ฌ๐ constructor.
There is a new feature in JavaScript called ๐๐ซ๐จ๐ฆ๐ข๐ฌ๐.๐ฐ๐ข๐ญ๐ก๐๐๐ฌ๐จ๐ฅ๐ฏ๐๐ซ๐ฌ.
Promise.withResolvers is a function that returns an object with two properties: a promise and a set of resolve and reject functions. This allows us to create a promise and manage its resolution or rejection in a more streamlined way.
In the example below, we use Promise.withResolvers creates an object with a promise and two functions resolve and reject. The asynchronous operation is simulated using setTimeout, and the appropriate function (resolve or reject) is called based on the outcome.
const { promise, resolve, reject } = Promise.withResolvers();
// Perform some async operation
setTimeout(() => {
resolve(‘Data fetched successfully!‘);
}, 1000);
promise
.then((data) => {
alert(data); // Output: ‘Data fetched successfully!’
})
.catch((error) => {
alert(error);
});
