[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.

閱讀「use client」參考頁面，以及關於伺服器端渲染和渲染樹的引文。結合連結文件的上下文和回報的伺服器端主控台輸出，驗證所描述的行為。完成標準是修改措辭，使其準確解釋 SSR 期間的 Client Components，同時不暗示標記為 client 的程式碼會被完全跳過。
