function User( properties ) {
    for ( var i in properties ) { (function(){
        this[ "get" + i ] = function() {
            return properties[i];
        };
    
        this[ "set" + i ] = function(val) {
            properties[i] = val;
        };
    })(); }
}

 

var user = new User({
    name: "Bob",
    age: 44
});
