What's the difference between writing 'Effect.Highlight(…)' and 'new Effect.Highlight(…)'?

Question

Both Effect.Highlight(...) and new Effect.Highlight(...) work just fine. So whats the difference in both usages, if any.

I started wondering about this because resharper (6) is showing me a warning when I use new Effect.Highlight(...): Expression statement is not assignment or call.

Manu.

Looks like the Highlight() function is static, so you can call it either way, but the simplest one will always work:

Effect.Highlight(...)

Whereas instantiating a new object might not (if the class isn't supposed to be instantiated)

However, Javascript is generally soft on those kinds of function calls, so I'm guessing you could also use:

(new Effect).Highlight(...)

as long as you enclose the instantiation in parenthesis so the interpreter will know what you're trying to do
