that's exactly where I've been the last couple of days. I need to learn the fundamentals and get a complete understanding before I jump into a framework. I'm not sure which is a good one out there, there are so many!!

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));

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.

Thanks for the examples, I'll have to break those down and try to understand them. The format looks pretty foreign to me...
