Example

From “what is this?” to “I get it”

What does this do?

const debounce = (fn, ms) => {
  let t;
  return (...a) => { clearTimeout(t); t = setTimeout(() => fn(...a), ms); };
};

It’s a debounce: it returns a wrapper that waits ms milliseconds after the last call before running fn. Each new call cancels the previous timer — great for search boxes and resize handlers.
