Learning JavaScript — Part 18

setTimeout

This method can be used when you want something to happen after a certain time. The argument of the amount of time is expressed in milliseconds (1s = 1000ms)

For example:

setTimeout(function() {
  console.log(`It's been five seconds!!!`)
  }, 5000);

setInterval

This method will run forever….

setInterval(function() {
    let i = new Date();
    console.log(`The Date and time is now ${i}`)
    
    }, 1000);

which results in

The Date and time is now Thu Oct 13 2022 16:09:39 GMT+0100 (British Summer Time)
The Date and time is now Thu Oct 13 2022 16:09:40 GMT+0100 (British Summer Time)
