Does it have calculator functionality?

It does. Might be a basic one, I suspect it's just sending your input to JS's eval function, but it gets the job done.

EDIT: I said it looks like JS eval because I put in `sqrt` and it showed me something like `function sqrt() { [native code] }`

When I tried to input some actual JS code it didn't do anything. I thought it might make for a basic REPL but no luck.
