Applies to: Array Object, String Object
The concat method combines the two arrays together.
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. |
Return value
Returns an new array consisting of a combination of two arrays.
Example
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 ConcatArray()
{
var a = new Array(0,1,2,3,4);
var b = new Array(5,6,7,8,9);
var c = a.concat(b);
return(c);
}
document.write(ConcatArray());
