JS中防抖和节流的区别是什么

如果我们要连续点击一个轮播图频繁地触发这个事件，这样可能会出现卡顿的情况，而防抖和节流的主要目的就是为了限制时间的连续触发。个人观点：1.防抖：我们在点击触发多次事件，它只会执行最后一次的点击。2.节流：我们在点击触发后，必须要等待时间过后再执行，多次触发是不会执行的。区别：区别就是节流不管我们触发多少次，它都必须在规定时间内执行这个函数，而防抖只会执行最后一次事件的函数。节流：先let a一....

JS中防抖和节流

防抖和节流是什么:防抖和节流是两种控制函数执行频率的技术，主要用于优化事件处理程序的性能。它们的主要区别在于执行时机和执行次数。防抖（Debounce）是一种在一段时间内无论触发多少次事件，都只执行一次事件处理程序的技术。具体来说，如果在设定的时间段内，事件被重复触发，则会重新计算延迟时间。例如，电梯第一个人进来后，等待15秒。如果过程中又有人进来，15秒等待重新计时，直到15秒后开始运送，这是....
