In programming, it is often important for a programmer to create fail-safes for themselves in case something goes horribly wrong. More often than not you would find that a previous version of your programme worked better but you don’t have that copy in existence any more. Thus, it is definitely essential for you to create backups of your programmes:
It helps you to compare different sections of your code that carry out the same function and provide you with clues as to which section of your code works the best to solve your mission.
It helps you to isolate the problem and prevent it from ever arising again.
It helps you to understand your code better in order to help you better solve any problems that might arise as you test your robot.
It helps to overcome the “Program unable to compile” error.
