[Typo]: Client Components running on the server

Summary

The "use client" docs state:

During render, the framework will server-render the root component and continue through the render tree, opting-out of evaluating any code imported from client-marked code.

The server-rendered portion of the render tree is then sent to the client. The client, with its client code downloaded, then completes rendering the rest of the tree.

This implies that Client Components are skipped during SSR, but I don’t think that’s true.

Details

My understanding is that Client Components will render on the server during SSR, and hydrate on the client. This is necessary so that the server-generated HTML is complete; if Client Components were truly skipped during SSR, our HTML would be full of holes that would only be filled in after hydration.

Another way to verify this is to add a console.log() to a Client Component, within a component function. The log will be printed in our server terminal, showing that the code is indeed evaluated on the server.

It’s possible I'm misunderstanding what is meant by "render" in this context, but it really makes it sound like the server skips any files that are marked with "use client". And unless this changed very recently, it is demonstrably untrue.

阅读“use client”参考页面以及关于服务器渲染和渲染树的引文。结合链接文档的上下文和报告的服务器端控制台输出，验证所描述的行为。完成标准是修改措辞，使其准确解释 SSR 期间的 Client Components，同时不暗示标记为 client 的代码会被完全跳过。
