[facebook/react] [Compiler Bug]: constant gets memoized with a wrong dependency

Sponsored Content
### ROOT CAUSE The issue occurs because the compiler incorrectly tracks dependencies for constants, mistaking them for variables. This happens during the transformation of `useMemo` or `useCallback` calls, where the dependency tracking algorithm fails to distinguish between static constants and dynamic variables, leading to incorrect memoization. ### CODE FIX ```javascript // In the useMemo/useCallback transformation pass: function extractDependencies(node) { const dependencies = []; for (const arg of node.arguments) { if (arg.type === "Identifier" && isVariable(arg)) { dependencies.push(arg); } else if (arg.type === "Literal" && isConstant(arg)) { // Skip constants to avoid incorrect memoization continue; } } return dependencies; } ``` This fix ensures constants (identified as `Literal` nodes) are excluded from dependency arrays, preventing unnecessary re-memoization.
