Writes modern, type-safe JavaScript using JSDoc annotations and the latest ECMAScript 2024/2025 features.
This skill optimizes Claude for authoring high-quality, modern JavaScript by enforcing type safety through JSDoc and TypeScript's checkJs engine. It guides the creation of robust codebases using the latest ECMAScript standards (ES2024/2025) and advanced Web APIs without the build-step overhead of a full TypeScript compilation. It is ideal for developers who prefer plain .js files but require the reliability of static type checking, sophisticated error handling, and efficient ESM module patterns.
