5. What is Git / Version Control?
It is a free and open-source version control
system used to handle small to very large
projects efficiently. Git is used to tracking
changes in the source code, enabling multiple
developers to work together on non-linear
development.
Git allow us to collaborate with large teams, each
person working on different aspect of the
project. The code can then be merged without
manually reading through every file to compare
changes.
