How to add field to each object in Javascript array without loop?

Question

Is there a way to add a field to each object of a Javascript array without looping over it?

something like

array.each(function (index, object){
  object[newField] = anotherArray[index];
});

@osrpt I want to use elements of functional programming where possible and was just wondering about the possibilities to do this in javascript. — nburk

I would say array.forEach (map, sum etc) is the functional programming alternative to classic looping — imcg

You might be interested in the differences between an Object ({}) and an Array ([]).

Currently, a cached length loop offers the best performance for an Array.
