Automatic fixes: Many problems ESLint finds can be automatically fixed with syntax-aware fixes.
Customization: Users can preprocess code, use custom parsers, and write custom rules alongside built-in rules.

Build and CI integrations: Documented integrations include Grunt, Webpack, Rollup, Git hooks, and CI-oriented tools such as Mega-Linter.
Language ecosystem: Plugins can add support for JavaScript extensions, TypeScript, React, Angular, Markdown, and other languages or frameworks.
Security reporting: Security vulnerabilities should be reported through GitHub's create-an-advisory form.
