Writing Code Like a Mathematical Proof

To write understandable code, always ask the question of who your audience is. What level of experience do they have? What are the prerequisites they should know before reading this function? There are even differences in the semantics between programming languages, so knowing the best practices, and the language coding style, will ensure you are writing readable code for developers in that language.
