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.
