函数防抖debounce与节流throttle

//防抖
function debounce(fn,delay){
    let timer = null
    return (...args)=>{
        if(timer) clearTimeout(timer)
        timer = setTimeout(()=>{
            fn.apply(this,args)
        },delay)
    }
}

// 节流throttle
function throttle(fn,delay){
    let late = +new Date()
    return function(...args){
        let now = +new Date()
        if(now - late > delay){
            late = now
            fn.apply(this,args)
        }
    }
}
