javascript await delay code example

Example 1: how to wait in javascript

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

//Pause for 1000 milliseconds

pause(1000)

Example 2: nodejs promise sleep

await new Promise(r => setTimeout(r, 2000));

Example 3: javascript async delay

const delay = (ms) => new Promise((resolve) => setTimeout(resolve, ms));

(async () => {
  console.log('1');
  await delay(1000);
  console.log('2');
})();

Example 4: javascript version of sleep

//Javascipt is asyncronous so you can't pause/block code execution
//You can delay doing something with setTimeout
setTimeout(function(){
 	alert("Sup!"); 
}, 2000);//wait 2 seconds
