como usar o debounce no javascript es6

January 04, 2020

Creates a debounced function that delays invoking the provided function until at least ms milliseconds have elapsed since the last time it was invoked.

Each time the debounced function is invoked, clear the current pending timeout with clearTimeout() and use setTimeout() to create a new timeout that delays invoking the function until at least ms milliseconds has elapsed. Use Function.prototype.apply() to apply the this context to the function and provide the necessary arguments. Omit the second argument, ms, to set the timeout at a default of 0 ms.

const debounce = (fn, ms = 0) => {
  let timeoutId;
  return function(...args) {
    timeoutId = setTimeout(() => fn.apply(this, args), ms);
  debounce(() => {
  }, 250)
); // Will log the window dimensions at most every 250ms
