DevGuru JavaScript METHOD: Array::concat

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)
