support for <string>.split("")

[nick]

Quick question...

It's my understanding that accessing a string as an array of
characters is a non-standard feature, not supported everywhere. I have
some code where I want to access a string as an array of characters.

When I call .split("") on a string (the argument is an empty string),
an array-like object is returned with each element being one character
of the original string. How widely supported is this behavior? Should
the example code below work in the major desktop and mobile browsers?

example code:

function something (str) {
if (!' '[0]) str = str.split('');
for (var i=0; i<str.length; i++) {
var c = str;
// do something with c...
}
}

TIA for advice.

don't use .split
use .charAt

don't use .split
use .charAt

Hmm, that would make sense now wouldn't it. Somehow I forgot that
function existed... thanks for reminding me.
