This repository provides a shareable ESLint configuration package (`eslint-config-notninja`) that standardizes linting rules for !ninja projects. By installing the package and extending `"notninja"` (or version‑specific presets like `"notninja/es6"` or `"notninja/esm9"`), developers get the recommended ESLint rules plus !ninja‑specific conventions for various ECMAScript versions and module types. It’s aimed at anyone building or maintaining JavaScript code under the !ninja brand who wants a ready‑made, consistent linting setup.
