Overview of linters

A linter is a software tool that analyzes codebase for bugs, errors, and other mistakes that impact its quality and can cause problems. Basically, each Qodana linter is associated with a specific programming language and helps you:

• Detect anomalous code and probable bugs

• Eliminate dead code

• Highlight spelling problems

• Improve overall code structure

• Introduce coding best practices

• Check third-party license compatibility. This feature is available in several linters

• Upload analysis reports to Qodana Cloud

Currently, several linters provide inspections for several programming languages.
