how to create a looping settimeout javascript code example

Example 1: settimeout inside loop

//you can leave the sleep constant
const sleep = (milliseconds) => {
  return new Promise(resolve => setTimeout(resolve, milliseconds))
}

const doSomething = async () => {
  for (/*for loop statements here*/) {
  //code before sleep goes here, just change the time below in milliseconds
   await sleep(1000)
  //code after sleep goes here 
    }
  }
doSomething();

Example 2: settimeout in a for loop javascript

// make sure to use "let" and not "var" if you want to capture
// the value of the external variable in a closure

  for (let i = 0; i < 5; i++) {
    setTimeout(() => console.log(i), 0);
  }
