JavaScript's new and map don't play well together

gistfile1.js

var todoViews = todoModels.map(function(todoModel) {
    return new TodoView(todoModel);
});

// if Function.prototype.new is defined or TodoView.new is defined using "this"

var todoViews = todoModels.map(TodoView.new, TodoView);

// if Todo.new is defined without using "this"

var todoViews = todoModels.map(TodoView.new);

@medikoo On Firefox, Object.create comes out the fastest. V8 obviously has some insane optimization for the bare constructor use (as mentioned before). I don't really worry about it...

@cjohansen on Firefox performance of Object.create vs new is not really different (it's slightly faster on benchmark that's it), on V8 it is noticeable in real world. Hopefully one day V8 will have it fixed. I also do not tend to worry about things prematurely ;)
