// Same as this:

var foo = 1,
    bar = function() {
        if (!foo) {
            var foo = 10;
        }
        alert(foo);
    };
bar();

for(var i = 0; i < myVar.length; i++) {
  (function($) {
    var new = myVar.property;
    // stuff
   //now you can use
   $.append(new)
  })(jQuery);
}

This works too

for(var i = 0; i < myVar.length; i++) {
  !function() {
    var new = myVar.property;
    // stuff
  }();
}
