Code Linting

Code linting is the process of automatically analyzing source code to detect programming errors, bugs, stylistic inconsistencies, and suspicious constructs. It uses static analysis tools called linters that scan code without executing it, identifying issues like syntax errors, undefined variables, or deviations from coding standards. This helps maintain code quality, consistency, and reliability across a codebase.

Also known as: Linting, Static Code Analysis, Code Analysis, Linter, Static Analysis

Why learn Code Linting?

Developers should use code linting to catch bugs early in the development cycle, enforce coding standards, and improve code readability, which reduces debugging time and technical debt. It is essential in team environments to ensure consistency, in CI/CD pipelines for automated quality checks, and for learning best practices, especially with languages like JavaScript or Python where dynamic typing can lead to runtime errors.
