Javascript React is a production-ready Claude Code skill (quality score 70/100) in the languages sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/javascript-react/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when asked to (1) write JavaScript code requiring advanced patterns like closures, proxies, generators, or async iterators, (2) build React applications with hooks, context, suspense, or server components, (3) optimize JavaScript/React performance, (4) implement complex state management, (5) write TypeScript with advanced type patterns, or when phrases like "React component", "JavaScript function", "TypeScript", "hooks", "state management", "frontend", "web app" appear.
The Javascript React skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems.
