Help w/ spread operator in RunJS

[rsarvis]

Sorry if this is not the proper place to ask this but...

I'm using RunJS to play with a line of code, but I'm getting an error that comes from trying to use the spread operator, so not sure what I'm doing wrong.

Shouldn't this work?
[...Array(10).keys()]

I just get SyntaxError: Unexpected token (...:1) so it's not accepting the Spread Operator. Is it a matter of the version of the language I'm using, and if so, how do I change that?

@rsarvis I'm not seeing any issues when running this:

What version of RunJS are you using?
