## What it is
Airbnb's widely adopted JavaScript style guide documenting coding conventions, naming rules, and best practices for modern JavaScript (ES5 through ES2018+). It ships with companion ESLint shareable configs (eslint-config-airbnb and eslint-config-airbnb-base) so the rules can be enforced automatically.

## Use cases
- enforce consistent javascript code style across a team
- set up eslint rules for a javascript project
- learn javascript best practices and conventions
- standardize naming conventions and arrow function usage
- configure a shareable eslint config for es6+
- onboard new developers to a common javascript style

## When to choose
- you want a battle-tested, community-standard JavaScript style guide with ready-made ESLint configs
- you need consistent code style across React or plain JavaScript codebases
- you want documented rationale for each style rule

## When to avoid
- you need a style guide for another language
- you prefer a minimal or fully customizable linting setup without opinionated defaults
- you need an executable tool rather than documentation and configs
