常规节流防抖

// 节流
export const throttle = (fn, time) => {
    let timer = null
    return (...args) => {
        if (!timer) {
            timer = setTimeout(() => {
                timer = null
                fn.apply(this, args)
            }, time)
        }
    }
}

// 防抖
export const debounce = (fn, time) => {
    let timer = null
    return (...args) => {
        clearTimeout(timer)
        timer = setTimeout(() => {
            fn.apply(this, args)
        }, time)
    }
}
