Definition and Usage
In JavaScript, the constructor property returns the constructor function for
an object.
The return value is a reference to the function, not the name of the function:
For JavaScript arrays the constructor property returns function Array() { [native code] }
For JavaScript numbers the constructor property returns function Number() { [native code] }
For JavaScript strings the constructor property returns function String() { [native code] }
You can use the constructor property to check if a variable is an array.
