throttle.ts

function throttle(func, delay) {
  let isThrottled = false;

  return function (...args) {
    if (!isThrottled) {
      func.apply(this, args);

      isThrottled = true;

      setTimeout(() => {
        isThrottled = false;
      }, delay);
    }
  };
}

// 使用示例
const throttledFunction = throttle(() => {
  console.log("Throttled function executed.")
}, 500)

// 调用 throttle 函数返回的函数，会在每 500 毫秒内执行一次
throttledFunction();
