About:
ESLint is a static code analysis tool designed to identify problematic patterns in JavaScript code. It parses code into an Abstract Syntax Tree (AST) to enforce custom coding standards and style rules, helping developers maintain consistent and error-free codebases. The tool is highly extensible through plugins and configuration files.
Key Features:
  • Extensible with plugins and shareable configurations
  • Built-in rules for identifying syntax errors and style issues
  • Fixes problems automatically via the --fix CLI option
  • Highly configurable via flat config files (eslint.config.js)
Use Cases:
  • Enforcing consistent coding styles across a team
  • Identifying bugs and anti-patterns before runtime
  • Integrating code quality checks into CI/CD pipelines
Alternatives:
  • Prettier – Prettier focuses strictly on code formatting, whereas ESLint analyzes code quality and style.
  • StandardJS – StandardJS is an opinionated, zero-configuration linter, while ESLint offers granular, customizable configuration.
