What does "Missing 'new' prefix when invoking a constructor" mean and how do I resolve it?

Question

I have created a function called CalcAge.  When I try to use it in a mapping, I get the above error.

Answer 1

QIE uses JSHint to validate javascript code. JSHint expects functions that start with a capital letter to be object definitions. To resolve this error you can rename your function to start with a lower case letter, or simply ignore the error message.
