Question

Accepted Answer

Ensuring code quality in large-scale systems involves best practices, tools, and team collaboration.

Implement code reviews: Regular peer reviews help catch issues early. For example, using tools like GitHub or GitLab for pull requests.
Automate testing: Use unit tests, integration tests, and end-to-end tests to ensure functionality. Tools like JUnit or Selenium can be helpful.
Continuous Integration/Continuous Deployment (CI/CD): Automate the build and deployment process to catch errors early. Tools like Jenkins or CircleCI are effective.
Static code analysis: Use tools like SonarQube or ESLint to identify code smells and enforce coding standards.
Documentation: Maintain clear documentation for codebases to ensure maintainability and ease of onboarding new developers.
