ESLint

ESLint is an open-source pluggable JavaScript and ECMAScript linting tool that statically analyzes code to identify and report on problematic patterns, code quality issues, and potential bugs to help developers write consistent, error-free JavaScript across browser and server environments. The tool integrates into most text editors and CI/CD pipelines, offering fully customizable rules and automatic fixing capabilities that enable teams to enforce coding standards, prevent common mistakes, and maintain high code quality throughout the development lifecycle.
