代码实现

    function throttle(func, time) {
        let runFlag = true;
        return function (e) {
            if (runFlag) {
                runFlag = false;
                setTimeout(function () {
                    func(e);
                    runFlag = true;
                }, time);
            }
        }
    }

    function debounce(func, time) {
        let timer;
        return function (e) {
            clearTimeout(timer);
            timer = setTimeout(function () {
                func(e);
            }, time);
        }
    }

    window.addEventListener("mousemove", debounce(function (e) {
        console.log(e);
    }, 1000))
