Git for Beginners: Basics and Essential Commands
Beginner's Guide to Git: Understand Commands, Workflows etc.
What is Git?
Git is a version control system that maintains track of the project. It makes switching between various versions of the project. It helps in undoing errors and modifications.
Why We Use Git?
Git is a version control system. If we make a mistake, we can't undo it without a version control system. We're losing track of what we changed. We can still handle these things when we're working alone, but it will be a mess when we work with other people on the same job. The other person can't see what and where we've changed, and none of us can see what and where they have changed.
It keeps the project on track.
We can revert the changes.
Helps in collaboration work
