JavaScript Mastery is a specialized Claude Code Skill designed to enhance developer productivity by providing immediate access to a deep knowledge base of core JavaScript principles. Inspired by the popular '33 JS Concepts' project, this skill assists in explaining complex behaviors like closures and the event loop, debugging tricky type coercion issues, and implementing idiomatic ES6+ patterns. It serves as an on-demand technical reference for refactoring legacy code, performing high-quality code reviews, and teaching the underlying mechanics of the JavaScript language to developers of all levels.
