**ESLint Plugin Ninja** is a whimsical yet functional ESLint plugin that adds a collection of “ninja‑style” linting rules—ranging from strict code‑style checks (e.g., enforcing emoji‑named variables, tab‑only indentation, aligned code) to tongue‑in‑cheek constraints (e.g., disallowing randomness, requiring luck, banning “woof”). It’s aimed at developers who want to experiment with unconventional, highly opinionated linting configurations for fun, learning, or code‑golf challenges, and can be added to any JavaScript/TypeScript project via the standard ESLint plugin setup.
