5 Concepts for Writing Clean Code

Learning to write clean code is a fundamental necessity for any piece of software. Coders who fail to practice this principle create room for mistakes such as bugs, glitches, and other roadblocks that can slow down the project. Organization is key, so here are some basic guidelines every developer should follow to create clean and fully functional code.

Single Responsibility Principle: each piece of code should have a specific function. A common misconception is that writing a function that carries out multiple purposes is more efficient and saves time. This can make it easy for mistakes to manifest spread to other functions throughout your program. Assigning one responsibility to one function will articulate organization and reliability, and it will be easier to fix mistakes later. Also, assigning one purpose to each function will make them reusable throughout your project.


Camel case: this is standard for naming variables. The first letter of the first word should be lower case, and every word after that should begin with a capital letter.


Use spaces and indents: many programmers fear that too many spaces, indents, and other ways of taking up more room may be wasteful, but the opposite is true. These make your code look more organized and easier to read. Don’t be afraid to take up the extra space to make your code more readable for you and your colleagues.


Avoid comments, so they don’t pile up and give you more work to wade through. Ask yourself: does this code need comments for my colleagues to understand? If the answer is yes, then you should consider going back and rewriting the code, so its meaning is clear and understandable to anyone who views it.


Revision: we’ve said before that the most critical stage of any project is the revision process. This is especially true for larger projects that you may have spent months working on completing. It’s easy to forget the places where you meant to review and improve. This will allow you to organize messy lines of code or trim them down to their essentials.
