Javascript: Can a string containing a newline "\n" be used as a property name?

Question

It is clear why I would not want to do this. But I have little choice in the matter.

Will browsers be able to handle this?

Chrome seems to be okay with it:

> var x = {};
> x['a\nb'] = 1;
1
> x
Object
a b: 1
__proto__: Object
> Object.keys(x)
["a
b"]

I guess it's okay, except the consoles might have a hard time displaying that. — John Dvorak, Dec 12 '12 at 22:44
Any valid string literal can be used as a property name (even an empty string, e.g. `x[''] = 1;`). — Šime Vidas, Dec 12 '12 at 22:46

Yes. Browsers should be able to handle that. You'll just have to use bracket notation to access that property.
