Can someone explain the “debounce” function in Javascript

Question

I am interested in the \"debouncing\" function in javascript, written here : http://davidwalsh.name/javascript-debounce-function

Unfortunately the code is not explai

Answer 1

This is a variation which always fires the debounced function the first time it is called, with more descriptively named variables:

function debounce(fn, wait = 1000) {
  let debounced = false;
  let resetDebouncedTimeout = null;
  return function(...args) {
    if (!debounced) {
      debounced = true;
      fn(...args);
      resetDebouncedTimeout = setTimeout(() => {
        debounced = false;
      }, wait);
    } else {
      clearTimeout(resetDebouncedTimeout);
      resetDebouncedTimeout = setTimeout(() => {
        debounced = false;
        fn(...args);
      }, wait);
    }
  }
};
