javascript async delay

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

                                    async function init() {
  console.log(1);
  await sleep(1000);
  console.log(2);
}

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

// one liner
let sleep = ms => new Promise(resolve => setTimeout(resolve, ms));

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

                                    const { promisify } = require('util');

const delay = promisify(setTimeout);

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