Definition
A linter is a utility that performs static analysis on source code without executing it. It checks for syntax errors, potential bugs, code smells, and deviations from style guides or best practices. By integrating linters into development workflows, teams ensure code consistency, improve readability, and catch issues early in the software development lifecycle. Popular examples include ESLint for JavaScript, Pylint for Python, and RuboCop for Ruby, which help maintain high-quality, maintainable codebases across large projects.
