What is Version Control System?

A version or Source control system is an application that keeps track of the project and manages changes to code.

Why do we need Version Control System?

Problem Statement

Let's assume we are building an application and it's working perfectly. Then you changed the code and now the application broke. Now it is very hard to find that old code. Version Control System solves this problem.

Solution

The version control system keeps track of all the files. If you change something it will store that and the main advantage is it will save the history of that project and if we want we can access that. So if we make any mistake and the application breaks we can revert back to any precious checkpoint.
