Math is not a function

wow, this is very old, any plans?

No - the issue is that built-in objects use a special internal variable type. We don't have such a variable type that can appear to be a function, and while with some effort one could be added, as far as I know Math is one of the only things like this - and I'm struggling to really think of real world cases where this matters.

It might be more sensible to add a 'differences' section to http://www.espruino.com/Features, mention this, and then close it. In fact I'll do that now.

Actually it looks like I misunderstood this issue. It's actually the opposite - built-in stuff in Espruino is all Functions (because for instance Number is usually actually a constructor) - but Math should be an Object - as should a bunch of other stuff - for example process or basically anything that you can't instantiate like E.

I think it's worth leaving this open - given it's actually a whole bunch of stuff it maybe worth adding that extra variable type.
