Description
Clean code is something that all programmers wish to code and maintain, but we tend to handle a lot of messy code that someone else has coded.
Here is a list of features that a clean code must-have.
- Clean code is easy to understand, modify, and maintain.
- Clean code doesn't contain duplicates.
- Clean code contains a minimal number of classes and moving parts.
- Clean code passes all the tests.
- Clean code is easier and cheaper to maintain.
Easy to understand, modify and maintain
- Easy to understand by someone new to the code.
- Programmers love modifying clean code.
- Clean code becomes less complex and easy to support and maintain.
Doesn't contain duplicates
- In case of duplicates, whenever we make changes to a duplicate code, we need to make sure the same change is made on every other instance of the duplicate code.
- Duplicate code slows down the development process.
Codebase size is small
- Less code means less maintenance and fewer bugs.
- Always try to keep the amount of code short and simple.
Passes all test cases
- Code is considered dirty when it passes less than 95% of the test cases.
- Code is non-reliable when test coverage is 0%.
Overall
We now know the features of clean code in software development.
