Now that looks even more like PHP....or should say, PHP looks more like JS...

Well, most languages these days have syntax that look similar to C, including PHP. However with Javascript there are a few things that differ to PHP (well in the current version of PHP in any case) like closures, lambda functions,o bject literals etc

javascript Code:

obj = {
    var : 'test',
    print: function() { 
        alert(this.var);
    }
};
obj.print();

javascript Code:

var obj = function () {  
    function doAlert(str) {
        alert(str);
    }
    return {  
        var : 'test',  
        print : function() {  
            doAlert(this.var);  
        }  
    };  
}();
obj.print();

javascript Code:

obj = function(){alert('Self invoked!'); }();

javascript Code:

getName = function(){
        namesArray = ['sam', 'ben', 'john','dave'];
        
        return function(n){
            return namesArray[n];
        };
    }();
    alert(getName(2));

But I would not spend to much time with the basic javascript and would jump right into a framework such as jquery.

Can't say I agree, I think a good understanding of how the language works (and ultimately how the framework works) is essential for performance if nothing else.
