Handling Forms & User Input

Why use debouncing with input validation?

const debounce = (fn, delay) => {
  let timeoutId;
  return (...args) => {
    clearTimeout(timeoutId);
    timeoutId = setTimeout(() => fn(...args), delay);
  };
};

input.addEventListener('input', debounce(e => {
  validateInput(e.target);
}, 500));

To make validation faster
To prevent validation errors
To reduce validation frequency
Debouncing input validation provides several benefits: 1) Reduces performance impact of expensive validation operations, 2) Prevents excessive API calls for remote validation, 3) Improves user experience by not showing error messages while typing, 4) Waits for user to finish typing before validating, 5) Particularly important for real-time validation or suggestions, 6) Helps prevent UI jank during rapid input.
