[Rails-spinoffs] merging one array into another

[Jeremy Kitchen]

Is there no better way to merge one array into another than iterating over the 
array you wish to append with each() and push()ing the elements on to the 
other array?

Here's what I mean:
var arr1 = [1, 2, 3, 4, 5];
var arr2 = ['a', 'b', 'c'];
$A(arr2).each(function(el) { arr1.push(el) });

Is there no better way to do it than this?

Thanks!
