We can achieve sleep in JavaScript by using setTimeout. The setTimeout function allows you to execute a function after a specified delay in milliseconds. Here’s an example:

function myFunction() {
 console.log("Hello after 2 seconds!");
}


setTimeout(myFunction, 2000); // This will log "Hello after 2 seconds!" after a 2-second delay.

If you need to handle more complex asynchronous operations, you can use Promises or async/await syntax.

Using Promises

function sleep(ms) {
  return new Promise(resolve => setTimeout(resolve, ms));
}

async function myFunction() {
  console.log("Start");
  await sleep(2000); // This will pause execution for 2 seconds without    blocking the program.
  console.log("End after 2 seconds!");
}

myFunction();

Using async/await

async function myFunction() {
  console.log("Start");
  await new Promise(resolve => setTimeout(resolve, 2000));
  console.log("End after 2 seconds!");
}

myFunction();
