constructor Property (Array)

constructor Property (Array)


Specifies the function that creates an array.


The required array is the name of an array.

The constructor property is a member of the prototype of every object that has a prototype. This includes all intrinsic JavaScript objects except the Global and Math objects. The constructor property contains a reference to the function that constructs instances of that particular object.

The following example illustrates the use of the constructor property.

var x = new Array();

if (x.constructor == Array)
    document.write("Object is an Array.");
    document.write("Object is not an Array.");

// Output:
// Object is an Array.
