Better than jQuery

MooQuery.js

var MooQuery = function (query) {
	this.elements = Array.prototype.splice.call(document.querySelectorAll(query), 0);
};

MooQuery.prototype = {
	constructor: MooQuery,
	each: function (callback) {
		this.elements.map(callback);
	},
};

// Examples

// Basic usage
// Make all links red

var links = new MooQuery('a');

links.each(function (element) {
	element.style.color = '#f00';
});

// Hide elements

MooQuery.prototype.hide = function () {
	this.each(function (element) {
		element.style.display = 'none';
	});
};

links.hide();

// Wow...
