CodeQL

CodeQL is a query language for code analysis developed by GitHub. It uses a combination of static analysis and machine learning to help developers find and fix bugs, security vulnerabilities, and performance issues in their code. CodeQL supports multiple programming languages and integrates seamlessly with GitHub's development environment. Key features include the ability to write queries in a high-level language, support for various code analysis tasks, and integration with GitHub's code review process. Use cases include code review, security auditing, and performance optimization. For example, a developer could use CodeQL to write a query that identifies potential security vulnerabilities in a piece of code.
