You're tasked with implementing a version control system for a large-scale web application. Which system would you choose, and what factors would influence your decision?

For a large-scale web application, Git is often the preferred choice due to its distributed nature, robust branching and merging capabilities, and strong community support. Factors influencing the decision include collaboration needs, scalability, and ease of branching. Git's popularity and extensive tooling make it suitable for large projects, allowing teams to work efficiently and manage complex development workflows.
