Lets say you want to call a function after 1s, 2s, 3s. You can use setTimeout, or you can wrap it up into a simple delay function that works with async/await We want to conver this code const run = (cb) =>{ setTimeout(()=>{ cb('1s'); setTimeout(()=>{ cb('2s'); se...
Learn how to write a promise based delay function and then use it in async await to see how much it simplifies code over setTimeout. Lets say you want to call a function after 1s, 2s, 3s. You can use setTimeout, or you can wrap it up into a simple delay function that works with...
