VUE3防抖和节流

    /* 防抖 */
    const myDebounce = (fn: () => void, delay: number | undefined) => {
        let timer: NodeJS.Timeout;
        return function () {
            if (timer) {
                clearTimeout(timer)
            }
            timer = setTimeout(() => {
                fn()
            }, delay)
        }
    };

    /* 节流 */
    const myThrottle = (fn: () => void, delay: number | undefined)=> {
        const isThtottle = ref(true)
        return () => {
