may/will happen. Version Control protects you when multiple people are coding in the same file. You also gain access to all prior versions of any file in your codebase
the folder. This will allow you to revert to any version of a file from the last 30 days. Be careful, this method will not prevent people from overwriting changes.
source control, it is very important that work is divided to reduce conflicts. If two people are working on the same file, there is no protection against overwriting your partner's work. The simplest solution is to never work on the same file at the same time. Note: This is the main reason to use real source control.
the challenge of using source control (git is the most popular), I will post links to some tutorials which can guide you. You can also contact me, with questions, and I will do my best to help you out.
