We have 3 methods:
//nodejs
const _sleep1 = require('util').promisify(setTimeout)
//nodejs
const _sleep2 = setTimeout[Object.getOwnPropertySymbols(setTimeout)[0]]
//js
const _sleep3 = m => new Promise(r => setTimeout(r, m))
Main function:
async function sleep(fn, ...args) {
if(args.length==0){
throw new Error("Require at least 2 parameters")
}
let timeout = args.pop()
await _sleep1(timeout) //can change to _sleep2, _sleep3
return fn(...args)
}
Example:
!(async ()=>{
await sleep(()=>{
console.log('Hello')
},2000)
})()
