Hi Dave, The "if/then" part of the statement may be obscured. Its called "the conditional operator", consists of the symbols "?:", and is the only tertiary (3 value) operator in javascript, or any other language that I know of. It works like:
result = (conditional expression) ? first value : second value ; If the "conditional expression" evaluates to something true, then the first value is returned as the result. If the conditional expression evaluates to something false, then the second value is assigned. Knowing this, I think you can go back and parse the expression.
