How did you approach working with legacy code in your project?

Answer from AI

When working with legacy code in a project, I usually follow these approaches:

  • Analysis and understanding — first, I study how the existing code works, what dependencies and features it has.

  • Test coverage — if there are no tests, I try to add them to ensure safe refactoring.

  • Step-by-step refactoring — I do not rewrite everything at once, but gradually improve the code, fix outdated constructs, and update libraries.

  • Documenting changes — I record what and why I changed so that the team is aware.

  • Using modern standards — for example, transitioning to newer PHP versions, using modern functions and approaches.

This approach helps minimize risks and improve code quality without losing functionality.
