typescript-and-javascript

What problem does it solve?

It solves inconsistent or error-prone TypeScript and JavaScript code quality by enforcing strict style and type safety requirements across all TS/JS file operations.

Core Features & Use Cases

• Consistent Type Safety: Prohibits any, requires strict equality, and prefers traceable typing using satisfies over type casting.
• Readable, Predictable Code: Encourages early returns, named functions (instead of arrow functions) where appropriate, and consistent control-flow formatting with curly braces.
• Scalable Code Organization: Discourages barrel exports and accidental logic in entry-point files (like index.ts(x)), improving maintainability and tree-shaking.

Quick Start

Use this skill when creating or editing any TypeScript or JavaScript files to ensure code follows the repository’s strict style and type-checking expectations.
