What is GitHub?
GitHub is a cloud-based platform that is widely used for version control and collaboration. It allows multiple people to work together on projects from anywhere in the world. Built around the Git version control system, GitHub provides a web-based graphical interface along with additional features such as access control, bug tracking, feature requests, task management, and wikis for every project.
Why GitHub?
The power of GitHub lies in its ability to facilitate collaboration among software developers. Its primary function is to host code and provide tools for version control, but it has evolved into much more. GitHub makes it easy for developers to track changes, revert to previous stages, and efficiently manage multiple versions of their projects. This is crucial in today’s fast-paced software development world, where team members often work on different parts of a project simultaneously.
