We try to merge consecutive reactive scopes that will always invalidate together, but there's one common case that isn't handled. ```js const y = [[x]]; ``` Here we'll create two consecutive scopes for the inner and outer array expressions. Because the input to the second scope is a temporary, they'll merge into one scope. But if we name the inner array, the merging stops: ```js const array = [x]; const y = [array]; ``` This is because the merging logic checks if all the dependencies of the second scope are outputs of the first scope, but doesn't account for renaming due to LoadLocal/StoreLocal. The fix is to track these temporaries. --- [//]: # (BEGIN SAPLING FOOTER) Stack created with [Sapling](https://sapling-scm.com).

React Compiler
React Compiler is a compiler that optimizes React applications, ensuring that only the minimal parts of components and hooks will re-render when state changes. The compiler also validates that components and hooks follow the Rules of React.
More information about the design and architecture of the compiler are covered in the Design Goals.
More information about developing the compiler itself is covered in the Development Guide.
