What actually is Git? 🔗
Imagine you are coloring on a flower coloring book. You colored in green for all leaves and now it’s time for the best part, coloring the petal. You know you enjoy red the best but it looked horrible after you finished it. With Git, you can revert your choice of red in a heartbeat and you are free to reapply the red if you change your mind. A work doesn’t have to be permanent; every action is recorded and reversible. (Source) – Git for a five year old
Git is basically a version control system. It was originally developed in 2005 by the same man behind the Linux operating system kernel, Linus Torvalds, for developers to actually contribute to Linux.
So, Git is a version control system, which means it tracks and manages changes to a project without overwriting that project. When developers are working on a certain project like an app, of course they make constant changes to the code. If they make a mistake, they can easily revert to its previous version. Because Git helps developers keep track of all the files in a project.
It also made collaborations easy for developers, allowing changes by multiple people to be merged into one source. It is totally useful whether you’re working solo, or as part of a team.

Now, what is GitHub? 💫
Github is a cloud-based hosting service where developers can publish and share their Git repos. It’s like a social network for programmers. While Git is a command-line tool, Github provides a web-based and desktop interface.
