METHOD:
Array::concat
Array.concat(arrayName2, arrayName3, ..., arrayNameN)
The concat method joins two or more Array objects producing
one new one. The original Array objects are unaffected by this
but, if one copy of a string or number is altered, it is not reflected
in the other, whereas a change to a referenced object can be seen in
both Array objects. The following example adds the elements of
the array 'cars' onto the array 'trees' on to the 'Cats' array:
Code:
Cats.concat(trees, cars)
