JavaScript style and best practices based on Google's official JavaScript Style Guide. This skill should be used when writing, reviewing, or refactoring JavaScript code to ensure consistent style and prevent common bugs. Triggers on tasks involving JavaScript, ES6, modules, JSDoc, naming conventions, or code formatting.

JavaScript and TypeScript best practices covering naming conventions, control flow, state management, TypeScript patterns (avoid any/enum, prefer type over interface), safety (input validation, assertions, error handling), performance optimization (reduce branching/looping, memoization, defer await, cache property access, storage API caching, avoid needless allocations, currying for hot paths), and documentation (JSDoc, comment markers). Use when writing JS/TS functions, refactoring code for performance, reviewing code quality, fixing type errors, optimizing loops or conditionals, adding validation, or improving error messages.

Write JavaScript/TypeScript for business applications (frontend and backend) with CRUD, API integration, and data transforms that are correct, readable, and easy to trust. Use when building or reviewing features involving forms, API responses, list/detail views, aggregations, or request/response shaping so outputs need minimal inspection.

Write JavaScript/TypeScript that is performant, readable, and easy to trust with minimal inspection. Use when generating or reviewing JS/TS code—scripts, utilities, data processing, or performance-sensitive logic—so outputs are correct, fast, and maintainable without heavy manual review.

Implement, refactor, or review worker-based multithreading in TypeScript/JavaScript apps (browser or Node). Use when offloading CPU-heavy loops to Web Workers, setting up a worker pool, moving data across threads, or diagnosing worker crashes, slowdowns, or synchronization bugs.

This skill should be used when the user asks to 'audit for JSR', 'check JSR readiness', 'review JSR config', 'verify package for JSR', 'publish to JSR', 'prepare for JSR publishing', 'JSR compliance check', 'run JSR audit', or wants to ensure their Deno/TypeScript package meets JSR standards before publishing.

Use when writing or reviewing UI copy - rewrites labels, CTAs, helpers, and placeholders through a Jobs to Be Done lens so every element reflects the user's actual goal, not the system's internal model.
