ecmascript-over-typescript-features

SKILL.md

TypeScript includes features like enum and namespace that are specific to TypeScript and don't exist in JavaScript. Prefer standard ECMAScript features when possible - they're more portable, better understood by the JavaScript ecosystem, and won't lock you into TypeScript-specific patterns.

This doesn't mean avoid TypeScript entirely - use its type system fully. But for runtime features, prefer standard JavaScript.

Prefer standard ECMAScript features over TypeScript-specific runtime features. Use TypeScript for types, JavaScript for runtime behavior.

Use when choosing between TypeScript and ECMAScript features. Use when writing portable code. Use when considering enum or namespace. Use when targeting multiple JavaScript environments. Use when writing library code. Source: marius-townhouse/effective-typescript-skills.
