concat Method (Array)

Description

Returns an new array consisting of a combination of two arrays.

Syntax

array1.concat(array2)

The concat method syntax has these parts:

Part	Description
array1	Required. An Array object to concatenate with array2.
array2	Required. An Array object to concatenate to the end of array1.

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.

The following example illustrates the use of the concat method:

function ConcatArrayDemo()
{
  var a, b, c;
  a = new Array(0,1,2,3,4);
  b = new Array(5,6,7,8,9);
  c = a.concat(b);
  return(c);
}
