JXA errors: "failed to get scripting definition", "Application can't be found"

System Events are two words. And if I remember correctly, var statements always yield undefined; you have to refer to the variable by name.

I'm getting these errors right off the bat:

=> undefined
>> SystemEvents = Application('SystemEvents')
!! Error on line 1: Error: Application can't be found.

Any ideas? Is there something I need to update or install before using JXA?

Looks fine to me. Application.currentApplicaton() is really not going to work with the REPL which is why you get that warning. Use the name of the application, path, etc.
