Common JavaScript File Extensions

The `common-js-file-extensions` package provides two static arrays, `code` and `config`, listing various file extensions associated with JavaScript code and configuration files, respectively. It includes extensions for a wide range of JavaScript dialects and transpiled languages, such as standard `.js`, `.mjs`, `.cjs`, as well as older or less common ones like `.coffee`, `.ts`, `.iced`, `.es6`, `.jsx`, and `.json5`. Currently at version 1.0.4, the package appears to be stable but likely no longer actively maintained, given its last update years ago (copyright 2016). Its primary utility lies in offering a comprehensive, if somewhat dated, reference for tools needing to identify JavaScript-related files without needing to parse package manifests or project configurations for specific language tooling.
