What is the main function of version control in web development?

Version control is a critical component in web development that primarily serves the purpose of tracking and managing changes made to code. This system allows developers to save different versions of their code, which is especially beneficial in collaborative environments where multiple developers are working on the same project simultaneously. With version control, developers can easily monitor modifications, revert to earlier versions if necessary, and understand the history of changes. This not only promotes better organization and efficiency but also aids in troubleshooting and maintaining a stable codebase.

The other options do not align with the core function of version control. Enhancing graphics pertains to design aspects, compiling code relates to transforming code into executable formats, and hosting involves placing a website on a server for accessibility; none of these roles involve the systematic tracking and management of code changes that version control provides.
