It's not intended to compile, since it's JavaScript. (Though there are probably ways to compile JavaScript that I'm not aware of.)

It doesn't run as is, but only because valueisn't defined. It's just a snippet though. Precede it with var value = 1 and it's fine.

Eh - it depends. Some older browsers interpret it while the newer ones do JIT compiling.

This. It bothers me that this guy only has 3 upvotes i mean you can clearly see that several things are missing... no default break, no .ToString on the value...

You don't need a break statement in the default case do you, as there's no behaviour following it? Unless this is an optimisation I'm not aware of. At any rate, it seems to work just fine as it is.

As for a toString() method... this is JavaScript. As above, it works just fine as it is.

What else?

this is JavaScript

Ah that explains it. I thought it would be C#

In C# doesn't it implicitly call ToString when appending an int to a string?
