KISS

KISS is an acronym for “Keep It Simple, Stupid” and was developed by the United States Navy in the 1960’s.

It states that most systems work best when kept simple rather than made complicated.

Advantages of simple code don’t need to be explained, we can all agree that we prefer reading and working with simple, yet expressive code instead of complex and hard to comprehend code.

Following this principle, you should always strive to keep your code as simple as possible and avoid any unnecessary complexity.

Examples on how to keep your code simple could be:

• Keep your methods and functions short, they should do what their name implies.
• If a method becomes too long, you can split it up in multiple methods
• Use expressive method/function and variable names, this increases readability of the code
