Naming

Common Principles​

  • Choose names that clearly describe the purpose. Names should be as short as possible but long enough to convey meaning.

  • Use full words instead of abbreviations.

  • Avoid reserved words as names.

  • Stick to a consistent naming convention throughout your codebase. For JS they are camelCase and PascalCase.

Variables​

  • Use nouns for variables.

  • Use Plurals for arrays and collections.

  • Except for loop indices, avoid using single character names.

  • Use named constants instead of hard-coding values directly in your code.

Functions​

  • Use verbs for functions (because functions are actions).

  • If the function is predicate the name is often starting with is, has, can, or should.

  • Function names should clearly indicate if they have side effects.
