FuncJS is intended to allow JavaScript programmers to get the basic areas completed quickly, and let them focus on more larger ...
Note that "truth" is interpreted very differently by the string-based #if function and the numerically oriented functions #expr and #ifexpr. A string is considered true if it contains at least one non-whitespace character (thus, for example, the #if function interprets the strings "0" and "FALSE" as true values, not false).
PHP generally follows C syntax, with exceptions and enhancements for its main use in web development, which makes heavy use of string manipulation. PHP variables must be prefixed by "$". This allows PHP to perform string interpolation in double quoted strings, where backslash is supported as an escape character.
In the above example, IIf is a ternary function, but not a ternary operator. As a function, the values of all three portions are evaluated before the function call occurs. This imposed limitations, and in Visual Basic .Net 9.0, released with Visual Studio 2008, an actual conditional operator was introduced, using the If keyword instead of IIf ...
