About Expressions ——— Printing Variables and Functions


When writing code in your stories, functions are special devices that can be used in expressions in place of variables or values.

Syntactically, they consist of:

  • a name, which is subject to the same rules that variable names are under,
  • followed by a ( left bracket,
  • followed by zero or more other expressions separated by commas,
  • followed by a ) right bracket.

Technically speaking, any Javascript built-in function is available to the Twine author: parseInt(), JSON.stringify(), document.createElement() and all the rest are accessible, as are any functions that have been added by scripts.
