DRY, KISS, YAGNI

DRY stands for Don't Repeat Yourself, which means you shouldn't write the same code over and over again. Instead, you should try to reuse code as much as possible to keep things efficient.

KISS stands for Keep It Simple, Stupid. It means you should try to keep your code simple and easy to understand. Don't overcomplicate things if you don't need to.

YAGNI stands for You Ain't Gonna Need It. This principle suggests that you shouldn't add functionality to your code unless you actually need it. So, don't waste time and effort on features that might not be necessary.
