Sync with react.dev @ 4c91abc7 #56
Conversation
Co-authored-by: OH HYUN KEUN <[email protected]>
This upstreams some of the [introduction post](reactwg/react-compiler#5) into the docs since this knowledge is quite fundamental to understanding the compiler, and it's confusing to not have it linked in the canonical source for the docs. It also adds more information about [debugging](reactwg/react-compiler#7) and reorganizes a few sections to make things clearer ghstack-source-id: ef32fc723722eb5119529abcc572dd2bcf2b1cab Pull Request resolved: reactjs/react.dev#6895

The docs for stylesheet precedence incorrectly state that there is an enumerated set of valid precedences. This is incorrect. The precedence value can be anything and React infers the hierarchy from the order in which it discovers precedences

Fix very minor typo
Added missing comma to the codesample.
Expo now has its own instructions for enabling the compiler.

Details
The global bundle is the javascript bundle that loads alongside every page. It is in its own category because its impact is much higher - an increase to its size means that every page on your website loads slower, and a decrease means every page loads faster.
Any third party scripts you have added directly to your app using the <script> tag are not accounted for in this analysis

Only the gzipped size is provided here based on an expert tip.
First Load is the size of the global bundle plus the bundle for the individual page. If a user were to show up to your website and land on a given page, the first load size represents the amount of javascript that user would need to download. If next/link is used, subsequent page loads would only need to download that page's bundle (the number in the "Size" column), since the global bundle has already been downloaded.
Any third party scripts you have added directly to your app using the <script> tag are not accounted for in this analysis
Next to the size is how much the size has increased or decreased compared with the base branch of this PR. If this percentage has increased by 10% or more, there will be a red status indicator applied, indicating that special attention should be given to this.
