What is version control system?
Version control, also known as source control, is the practice of tracking and managing changes to software code. And Version Control System is a system which helps in the accomplishment of the Version Control.
We're not diving into details of the version control system.
Git Is a Distributed Version Control System which allows you pull (copy the complete code from directory) and push (Push your code into repository), create branches in the alongside main repository where you can work without disturbing the main repository and merge the code whenever required.
It saves you when the everything goes sideways, it can revert back the code to its previous version or commit.
I have given a table below which can be used as a cheat-sheet and you can take screen-shot of it as well for the future use.
