Holy shit! Its a f**king example, its not a JS library to replace jQuery or Prototype. It is simply showing you how the core of jQuery is built

In prototype you can do:
$('mydiv').innerHTML = "Hello everybody";

The code above does not allow you to do that… :p

That is why mootools is modular

Nice work Dustin.

@Chris: “There are times when using a JavaScript library is called for…” i read this somewhere.

Sorry, but what is the point with that? You can do that with mootools core functions and elements extensions…
$$(‘#foo’, ‘#bar’).addEvent(‘click’, function(){
this.setStyles({
‘color’: ‘green’,
‘fontSize’: ’2em’
}).addClass(‘active’);
});

it is neither news, nor it is something special, so what is the point?

To be fair, this isn’t “all” of jQuery in 54 lines. It was just a couple of the core functions. And by no means is it a replacement, or a released js library – this was just a sample implementation of a couple functions that has a cool chainable interface :)

it is a function that call itself,the reason to do this is to keep the global namespace clean so the _$ is local to the function but the $ function is exposed because it is append to the global namespace(i.e. window).

Is that console.log in the css function left in there on purpose?

Neat stuff. Maybe some simplified version of Prototype’s Ajax object and it’ll be all I need. Also, can someone explain to me what the parentheses around the function do? Like

(function (){ ... })();
Is this another way to create objects? Thanks in advance for any help.

jQuery in 54 lines ;)

Basically, Dustin is reinventing jQuery =P

I wholeheartedly agree though and am currently in a similar process of thought. jQuery can be a whole lot less bulky (and it’s small to begin with) and it seems they’re headed towards the same mentality as well.

ps. I’m not on the pro-jQuery bandwagon, we use prototype ourselves as well at my company…
