debounce.js

function debounce(func, delay) {
  let timerId;

  return function (...args) {
    clearTimeout(timerId);

    timerId = setTimeout(() => {
      func.apply(this, args);
    }, delay);
  };
}

// 使用用例
const debounceFunction = debounce(() => {
  console.log("Debounced function executed.");
}, 500);

// 调用 debounce 函数返回的函数，会在最后一次调用后延迟 500 毫秒执行
debouncedFunction();
