Creating and Resolving Promises with Promise.withResolvers() (ES15)

Problem: I needed a quick way to create a promise and have control over its resolution or rejection externally, while being able to use the promise later.

Solution: By using a utility like Promise.withResolvers(), I can instantly create a promise along with its resolve and reject functions, allowing control over when the promise is fulfilled.

const [promise, resolve, reject] = Promise.withResolvers();

setTimeout(() => resolve('Resolved after 2 seconds'), 2000);
promise.then(value => console.log(value)); 
// Logs: "Resolved after 2 seconds"

Keywords: JavaScript promise, Promise.withResolvers, resolve and reject functions, external promise control, promise utility, asynchronous control, promise handling
