A debounce that makes more sense to me (written by myself)

debounce.js

function debouce(fn, wait = 99) {
  let timeout = null;

  function process(args) {
    fn(args);
    timeout = null;
  }

  return function() {
    if (!timeout) {
      timeout = setTimeout(process.bind(null, arguments), wait);
    } else {
      clearTimeout(timeout)
      timeout = setTimeout(process.bind(null, arguments), wait)
    }
  }
}
