constructor

Summary

Specifies the function that creates a Number.

Syntax

number.constructor

Examples

The following example illustrates the use of the constructor property.

var num = new Number();

 if (num.constructor == Number)
     document.write("Object is a Number.");
 else
     document.write("Object is not a Number.");

 // Output:
 // Object is a Number.

Remarks

The required number is the name of a string.

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.
