7.9.1 concat Method

Combines two arrays to create a new array.
Syntax
array1.concat(array2)
Arguments
- array1
- An Array object to concatenate with array2. Required.
- array2
- An Array object to concatenate to the end of array1. Required.
Remarks
The concat method returns an Array object containing the concatenation of array1 and array2.
If an object reference is copied from either array1 or array2 to the result, the object reference in the result still points to the same object. Changes to that object are reflected in both arrays.
