setTimeout vs setInrerval?

Question

Hello guys, I actually wanna know this what's the difference between setTimeout and setInterval in JS?

Answer 1

For example:
setTimeout(function() { alert('foo');}, 1000);
- waits for 1000 milliseconds, then runs the callback function (alerts 'foo') in this example

setInterval(function() { alert('foo');}, 1000);
- triggers callback every 1000 milliseconds. Meaning you'd get 'foo'-alerts every 1000 milliseconds, until you call the clearInterval-function to stop it.

Thank you
