Repeating a code is quite problematic. Here's why - We ll have to write more code obviously, but this is not the main problem. - Main problem is maintaining those codes. Suppose we have to make some change then we ll have to apply that change on all the repeated places. It's a big headache. That's why programmers sometimes goes to great lengths to keep it DRY using various complicated design patterns. I have a simple example here to demonstrate the benefits of keeping it DRY. In this code we can clearly see DRY is missing and same function is repeated, hence the long code & painful future efforts to add colour. https://code.sololearn.com/WFc1NNwxG2q8/?ref=app But a refactoring attempt with DRY in mind can greatly reduce the effort ( future efforts too). https://code.sololearn.com/WJPh1bqz0VFd/?ref=app Ending Notes: Although writing DRY codes might look easy but it ll come with practice , study, knowledge of language & design patterns. DRY principle is applicable to all programming languages

Even the simple use of functions/methods is an example of DRY I believe.

Don't repeat yourself: used to help programmers save on memory by not writing the same code over and over
