Question

I understand that debounce in Undercore.js returns a function that will postpone its execution until the wait time is over.

My question is, is there an adva

Answer 1

They are very different and used in completely different cases.

1. _.debounce returns a function, setTimeout returns an id which you can use to cancel the timeOut.

2. No matter how many times you call the function which is returned by _.debounce, it will run only once in the given time frame.

var log_once = _.debounce(log, 5000);

function log() {
  console.log('prints');
}

log_once();
log_once();
log_once();
log_once();
log_once();

var id = setTimeout(function() {
  console.log('hello');
}, 3000);
clearTimeout(id);
