A jQuery-like global JavaScript selector core

javascript.$.js

var jQuery = (function() {

	// Define a local copy of jQuery
	var jQuery = function( selector, context ) {
		// The jQuery object is actually just the init constructor 'enhanced'
		return new jQuery.fn.init( selector, context );
	};
	
	jQuery.fn = jQuery.prototype = {
		init: function( selector, context ) {
			this.selector=selector.style?selector:document.getElementById(selector);
			return this;
		},
		// Start with an empty selector
		selector: ""
	}

	// Give the init function the jQuery prototype for later instantiation
	jQuery.fn.init.prototype = jQuery.fn;


	// Expose jQuery to the global object
	return (window.jQuery = window.$ = jQuery);

})();

console.log(jQuery);
console.log($);
console.log($('text'));
