eslint-config-airbnb-base

15.0.0 verified Sat Apr 25 auth: no javascript

Airbnb's base ESLint config (without React) for enforcing consistent JavaScript style, version 15.0.0. Provides two configs: 'airbnb-base' for ES6+ and 'airbnb-base/legacy' for ES5 and below. Requires peer dependencies eslint ^7.32.0 || ^8.2.0 and eslint-plugin-import ^2.25.2. Actively maintained as part of the Airbnb JavaScript style guide. Differentiators: widely adopted, opinionated ruleset, and explicit support for legacy environments.
