eslint-plugin-no-function-declare-after-return

An ESLint plugin that enforces a code style rule disallowing function declarations after a return statement within the same scope. Version 1.1.0 is the latest stable release, with auto-fix support added in this version. The plugin is mature, actively maintained, and has no known security issues. It differs from ESLint's built-in no-unreachable rule by focusing specifically on hoisted function declarations after return, which are syntactically valid but harm readability. The plugin is lightweight with zero runtime dependencies besides ESLint.
