What Is Git And Why Is It So Popular?

Git is the most popular Version Control System in the world. A Version Control System records the changes made to our code over time in a special database called a repository.
 
We can look at our project history and see who has made what changes, when, and why. And if we screw something up, we can easily revert our project back to an earlier state.
 
Without a Version Control System, we’ll have to constantly store copies of the entire project in various folders, this is very slow and doesn’t scale at all especially if multiple people have to work on the same project. You would have to constantly toss around the latest code via email or some other mechanisms and then manually merge the changes.
 
So in a nutshell with a Version Control System, we can track our project history and work together now version control systems fall into two categories.
 

Centralized Version Control System

In a centralized system, all team members connect to a central server to get the latest copy of the code and to share their changes with others subversion and the Microsoft team foundation server is an example of centralized version control systems. The problem with centralized architecture is the single point of failure, if the server goes offline we cannot collaborate or save snapshots of our project so we have to wait until the server comes back online.
 

Distributed Version Control System

In distributed systems, we don’t have these problems every team member has a copy of the project with its history on their machine. So we can save snapshots of our project locally on our machine if the central server is offline we can synchronize our work directly with others. Git and Mercurial are examples of distributed version control systems out of all these Git is the most popular Version Control System in the world. Because it’s Free, Open Source, Super Fast, and Scalable. Operations like Branching and Merging are slow and painful in other Version Control Systems.

 

Git is Everywhere

So Git is almost everywhere more than 90% of software projects in the world use Git. That’s why almost every job description for a Software Developer mentions git. So if you’re looking for a job as a software developer git is one of the skills you must have on your resume.
