@skghost
Have a read through the executing the compare() function

Please read
http://www.codecademy.com/forum_questions/559dcb4be39efe550f00006b
and concentrate on:

  • the creation of the compare function
  • the truth-table
  • the build of the IF ELSE-IF statement structure as part of the compare FUNCTION-BODY
  • the execution of the compare function (keeping in mind that the return statement is used )

Hi @skghost,

What is this bit of code at the bottom supposed to do:

userChoice(choice1)
computerChoice(choice2)

and where do you call your compare function?

@msfrisby,
That code is called an UFC
unidentified flying code

@leonhard.wettengmx.n Hahaha :joy: Once I start writing longer programs I'm sure to become the reigning champ of UFC... the truth is out there!
