Question

I’m looking to understand exactly what the symbol is bound to and how it was bound, and what its underlying structure looks like.

I’m guessing it’s done with a label but I’m not experienced enough with JavaScript to be sure.

Answer 1

Odd question. The $ symbol is just an alias for jQuery.

So, instead of this:

jQuery('a').css('color','#f00');

…You can do this:

$('a').css('color','#f00');

It doesn’t necessarily need to be $ either. If you like, you can ADD MORE MONEY. This works:

(function ($$$$$$) {
    $$$$$$('body').html('Nobody will mess with you when you have this much cash.');
}(jQuery));

It seems as though normal JavaScript variable naming rules apply:

• Variable names must begin with a letter
• Variable names can also begin with $ and _
• Variable names are case sensitive

If you wanted, your alias could be orange_peanut, but let’s not do that for obvious reasons.

Hope that helps! 🙂
