防抖(debounce)与节流(throttle) 2.0

export const debounce = (fn, delay = 1000) => {
	let timer = null;
	return function () {
		if (timer) {
			clearTimeout(timer);
			timer = null
		}
		timer = setTimeout(() => {
			fn.apply(this, arguments);
			timer = null;
		}, delay)
	}
}

export const throttle = (fn, delay = 1000) => {
	let _arguments = arguments
	let canRun = true
	return function () {
		if (!canRun) return
		canRun = false
		setTimeout(() => {
			fn.call(this, _arguments)
			canRun = true
		}, delay);
	}
}

用法

fun:throttle(function(){	
	...
},5000),
//如果带参数的话
fun:throttle(function(e){	
	console.log(e)
},5000),

ps:在编辑器中fun的颜色可能会跟其他的方法名不一样，但是是可以用的
