Promises with setTimeout()
We can create a Promise and resolve it after a certain delay using setTimeout(). This allows for better handling of asynchronous operations.
Syntax:
const delayedFunction = (delay) => new Promise(resolve => setTimeout(resolve, delay));
Example: Printing the output at a delay of 3 seconds using Promises with setTimeout().
const delayedFunction = (delay) => new Promise(resolve => setTimeout(() => {
console.log('Function called after ' + delay + ' milliseconds');
resolve();
}, delay));
delayedFunction(3000);
Output:
