Clean code revolves around crafting solutions that are both elegant and efficient.
The main thing to be kept in mind while coding is keeping code clean, more readable, and more efficient with these tips.
Clean code isn’t about perfection; it’s about communication.
It’s like writing it just for later you (or your team), so that it is clear to know , what are the projects you worked on . It should such a way someone not part of your should be able to understand.
Tips
1. DRY Principle - Dont repeat yourself
Keep your methods short .
Rule: There should be a method with a single purpose which performs that purpose adequately. Make use of functions and loops.
Shorter_ methods_ make testing easier and debugging faster.
2. Name things in such a way that anyone can understand.
Clear is better than clever.
Your code shouldn’t be a puzzle. Variables, classes, and methods should have names indicating their purpose.
Avoid this:
int x = calculate(a, b);
Instead:
int sum = calculateSum(firstNumber, secondNumber);Readable code is easy to maintain.
3. Comment with purpose
Use comments to clarify, not for storytelling.Code as if the person maintaining it later is an newbie. Prioritize clarity and empathy—include meaningful error messages that provide precise guidance and make troubleshooting less burdensome.
4. Follow a consistent formatting style
Formatting is about readability and also makes code look better.
5. Avoid over-doing.
Keep your solutions as simple as possible.
For example, there is no need to use a custom iterator if it can be solved using a for-loop.
