Understanding Debouncing in JavaScript

Understanding Debouncing in JavaScript

What is Debouncing?

Debouncing is a technique to limit how often a function is executed. It's commonly used in input fields or scroll events to improve performance.

function debounce(fn, delay) {
  let timer;
  return function (...args) {
    clearTimeout(timer);
    timer = setTimeout(() => fn.apply(this, args), delay);
  };
}

How It Works

This function returns a debounced version of the input function. It ensures that the function only runs after the user stops triggering it for the specified delay.
