Linters are tools used to analyze code for potential errors, bugs, and violations of coding standards. They help developers identify and fix issues early in the development process, improving code quality and consistency.

Linters check code against a set of predefined rules or guidelines, which can vary based on the programming language or specific project requirements. These rules often cover various aspects of coding practices, such as syntax errors, code formatting, and adherence to best practices.

By integrating linters into the development workflow, teams can automate code review processes, ensuring that code meets quality standards before it is committed or merged. This automation reduces the likelihood of introducing bugs or inconsistencies and helps maintain a clean and maintainable codebase.

Linters can be configured to fit the specific needs of a project or team, allowing for customized rule sets and levels of strictness. Some linters also provide auto-fixing capabilities, which can automatically correct minor issues, further streamlining the development process.

Overall, linters are essential tools for enhancing code quality and enforcing coding standards, contributing to more reliable and maintainable software.
