Where in the source is useState defined?

Based on the available data, I cannot definitively tell you the exact file location where useState is defined. The search results only show it being imported from the 'react' package and used throughout the codebase, but the actual implementation file is not present in the retrieved data. useState would typically be defined in the main React package source (likely in packages/react/src/), but the specific file path is not included in the data I have access to.
