Keep your code DRY

DRY is an acronym for Don't Repeat Yourself which means that you should not write more code than necessary to get your job done. While keeping things simple and avoiding unnecessary repetition sounds like a good idea, it's not always easy to do in practice. The idea behind the DRY technique is that it's better to use one function or method that does many things than multiple functions or methods that do the same thing. It's a principle of software development that makes it easier to maintain, update and even change your code. A lot of people think DRY means "don't write more than once," but in reality, this isn't the case at all. Instead, it means only writing one piece of code for a given task instead of multiple pieces that does the same thing.

Keep your code DRY to save time and cost.

Keeping the code DRY is an important aspect of developing software as it helps you prevent errors, and saves time. Keeping your code clean and easy to read makes it easier for you, as well as other developers on your team, to troubleshoot issues that might arise with their work. If there is an issue with one part of your application, it's much easier for someone else to maintain it as opposed to when everything is mixed in one big ball of mud! This means fewer bugs in production. And with fewer bugs in production, there's less downtime.

Benefits of Keeping the code DRY

Readability: A good way to do this is by keeping different parts of a program separate so that they can be worked on independently without affecting each other. Keeping code DRY means that you keep your code simple and clean. That makes it easier for others to understand what you’re trying to do, and easier for other developers on your team to read and modify.

Maintainability: When working on something small like adding a new feature or fixing a bug, it's easier for us humans (and even machines) if we're not dealing with huge chunks of messy code that looks like gibberish. Keeping your code DRY also makes it easier for you (and any future developers) to make changes later on down the road.

Performance: By keeping your code DRY, your apps will run faster because they won't have duplicate functionality among different files or modules. This also makes debugging easier because any changes made are immediately reflected across all files using the same function or method name; this way developers know exactly what's happening when debugging issues occur during development time rather than having several different variables defined within each file which can be confusing when trying to figure out why something isn't working properly.

Conclusion

The biggest takeaway here is that you should keep your code DRY. There’s no doubt about it; the more code you have in your project, the harder it is to maintain, test and update. This makes development much more time-consuming and costly for businesses looking for ways to save money by cutting down on expenses like maintenance costs related to software developers. Keeping your code dry will save time, and it will help you troubleshoot problems easily. If you follow these simple tips, then hopefully you'll have a clean codebase.
