Version control is an incredibly important skill that every developer should master, and Git is one of the most popular version control systems used in the workforce. Whether you're working as a solo developer or working with a team, being able to track the history of a project is paramount. Tracking versions of your code will help you keep a record of progress and allow you to "undo" any blunders that occur along the way. This is incredibly important in a profession where ~96% of developers say they work on a team of engineers all working on the same code and ~67% of developers report having to check-in changes in their code at least once a day.
