We’ll start by creating a simple function that takes one parameter which is the total time we want to delay execution for. The function will return a Promise
which will be resolved after the timer finished.
const delay = time => new Promise(resolve => setTimeout(resolve,time));
That’s basically it! Here are a couple of javascript tips & tricks if you’re not familiar with the Javascript ES6 syntax.
Now you can use your function like this:
// You can call the function and use .then();
delay(5000).then(() => console.log('Hello World'));
// You can also use async/await
async function counter() {
console.log(1);
await sleep(1000);
console.log(2);
}
count();
Here you can find more details about async/await in javascript.
