[Suggestion]: Document unsupported syntax in React Compiler (e.g. inside try/catch) #8685
Description
Summary
Document unsupported syntax in React Compiler (e.g. inside try/catch)
Page
https://react.dev/learn/react-compiler
Details
React Compiler silently skips components it can't compile, which is intentional (panicThreshold: 'none'). But the docs don't say which patterns trigger a skip, so developers can't tell when a component isn't being optimized.
A write up reports that these patterns inside try/catch prevent compilation:
- conditionals (
if/else) - ternaries, optional chaining and
?? throw
The compiler's own error confirms at least one of these: Todo: Support value blocks (conditional, logical, optional chaining, etc) within a try/catch statement.
These are common in async code (fetch, then check response.ok), so developers may be affected without knowing.
Request:
Add a list of currently unsupported syntax patterns
