        var value = str.constructor; 
        document.write(value);

The String constructor property in JavaScript is used to return the string constructor function for the object. The function which is returned by this property is just the reference to this function not a string containing the function’s name. The JavaScript number constructor, string constructor and boolean constructor returns function Number() { [native code] }, function String() { [native code] } and function Boolean() { [native code] } respectively.

Syntax:

string.constructor

Return Value: function String() { [native code] }

<!DOCTYPE html>
