简版防抖节流函数

节流函数

function throttle(func, delay) {
   let lastTime = 0;
   return function () {
     const now = Date.now();
     if (now - lastTime >= delay) {
       lastTime = now;
       func.apply(this, arguments);
     }
   };
 }

 const throttledFunction = throttle(
   () => console.log('节流函数'),
   1000
 );

防抖函数

function debounce(func, delay) {
   let timeoutId;
   return function () {
     clearTimeout(timeoutId);
     timeoutId = setTimeout(() => {
       func.apply(this, arguments);
     }, delay);
   };
 }

 const debouncedFunction = debounce(
   () => console.log('防抖函数'),
   1000
 );
