ESLint is the linter the JavaScript world standardized on. The plugin ecosystem is its real moat: every framework, library, and accessibility rule has an ESLint plugin. The flat config (eslint.config.js) shipped in v9 cleaned up years of config debt. ESLint is slower than Biome on large repos and has a heavier mental model, but for most teams the plugin coverage and editor integration are reason enough to stay. Pairs with Prettier for formatting.
