响应式

Reactivity

Leptos 构建在细粒度响应式系统之上，旨在尽可能低频地运行昂贵的副作用（例如在浏览器中渲染内容或发起网络请求）以响应响应式值的变化。

Leptos is built on top of a fine-grained reactive system, designed to run expensive side effects (like rendering something in a browser, or making a network request) as infrequently as possible in response to change, reactive values.

到目前为止，我们已经看到了信号（signal）的实际运行。这些章节将进行更深入的探讨，并研究响应式系统的另一半：副作用（effect）。

So far we’ve seen signals in action. These chapters will go into a bit more depth, and look at effects, which are the other half of the story.
