ESLint adoption guide: Overview, examples, and alternatives

ESLint remains the leading tool for linting JavaScript and TypeScript projects as of 2024, owing to its configurability, extensive plugin ecosystem, and support for custom rules, which makes it adaptable to a wide range of coding styles and project requirements. The current version, 9.7, introduces significant changes, including a flat configuration file system that simplifies setup and usage. ESLint helps developers identify potential runtime bugs, enforce coding standards, and maintain code quality by offering customizable linting rules and integrating seamlessly with various development environments and CI/CD pipelines. Its extensibility allows it to support TypeScript and JavaScript syntax extensions, such as JSX, and frameworks like React and Vue. While new competitors like Biome and quick-lint-js have emerged, offering features like code formatting and real-time feedback, ESLint's comprehensive capabilities and continuous improvement make it a preferred choice for maintaining clean, consistent codebases, especially in commercial settings.
