typescript-typing

What problem does it solve?

This Skill helps improve code quality and maintainability in JavaScript-first projects by incrementally adding TypeScript-like typing, without a full migration.

Core Features & Use Cases

• Strengthen JavaScript Types: Use JSDoc and declaration files (.d.ts) to define and enforce types.
• Shared Type Definitions: Promote reusable types to shared definition files.
• Use Case: You have a complex JavaScript function with many parameters. Use this Skill to add JSDoc type annotations to clearly define each parameter's expected type and shape, making the function easier to understand and use.

Quick Start

Use the typescript-typing skill to add JSDoc type annotations to the function calculateTotal in src/utils.js.
