You may have heard the term of DRY, D-R-Y, which stands for don't repeat yourself. The DRY principle is especially true in software development because software is great at grouping redundant tasks. It might sound intimidating to think about reusable code when we're starting out in software development, but it is actually pretty straight forward. The good news is DRY is almost always a gradual process. We could start small and gradually group together bigger chunks of code to make them more reusable.
