Throttleexample

In this example, we define a throttle function that takes a callback and a delay as arguments. The throttle function returns a new function that wraps the callback with a logic that uses setTimeout to create a timer. The timer ensures that the callback is

throttle 函数签名: throttle(durationSelector: function(value): Observable | Promise): Observable 以某个时间间隔为阈值，在 durationSelector 完成前将抑制新值的发出\ 示例 示例 1: 节流2秒，时间由第2个 observable 决定 ( StackBlitz | jsBin | jsFiddle )

You can use in a screen or component for all of the functions you want to throttle, and they will share the same throttle. Or you can call useThrottle() multiple times and have different throttles for individual functions.

本文介紹什麼是節流 (throttle) 函式，以及如何實作節流 (throttle) 函式。 節流 (throttle) 可以用來優化程式碼，避免在短時間內重複執行相同的函式。

The throttle function in this example accepts two arguments: func, the function to be throttled, and delay, the minimum interval between calls to func. A new function that encapsulates func and executes the throttling logic is returned by the throttle fun

這篇文章將會探討 debounce 和 throttle 這兩種用於最佳化事件處理的關鍵技術，並且詳解如何自己手寫實作 debounce 和 throttle。
