BTW, If you use this in Functional.js then you will have to change this line:

if (specialized[i] == _)

to this:

if (specialized[i] === _)

Hi, that’s a great writeup of a neat technqiue. Thanks.

Some minor typos: L1 L1 and L2 L2 are missing their == comparison operator. the ‘pre’ tag has snuck into your post.

Interesting.
We could of course go even further and support n-level nesting (which is not exactly the point of the article, but is still entertaining)

[code]
function defineLiteral() {
var o = window, args = arguments, prop;
for (var i=0, l = arguments.length; i prop = arguments[i];
o[prop] = o[prop] || { }; o = o[prop];
if (i == l-1) o['toString'] = function() {
return Array.prototype.join.call(args, '.')
}
}
return o;
}

defineLiteral('bar', 'baz', 'qux', 'quux'); // => bar.baz.qux.quux
bar.baz.qux.quux.toString(); // => 'bar.baz.qux.quux'
[/code]
