How to Write Clean Code?

Basic Hygiene

  • Leave the place cleaner than you got it.

Naming Convention

  • Do one thing in a function. Name should reflect the action. Function name is a verb.
  • Declare literals ([a-z]+, [0-9]+) as constants.

Functions

  • The function should not exceed twenty lines.
  • Each if, else, while statement can become a function.
  • The function can have one or two levels of indentation.
  • A function must do only one thing. The one thing is discovered when function can’t be reduced further. The reduced name is similar to the function’s current name.
