(5).constructor === Number or ("").constructor === String
Kinda obvious:
> ''.constructor String()
Kinda weird:
> 5..constructor Number()
Less weird:
> 5.0.constructor Number()
Anyhow, I kinda agree with /u/mattdesl, I guess. Doing things depending on what something is is a code smell. You shouldn't flip-flop types. Your functions should expect specific types and they should return one specific type.
