The constructor property returns a regular expression's constructor function:

var patt = new RegExp("Hello World", "g");
var res = patt.constructor;

Definition and Usage

The return value is a reference to the function, not the name of the function:

For JavaScript regular expressions the constructor property returns function RegExp() { [native code] }

For JavaScript numbers the constructor property returns function Number() { [native code] }

For JavaScript strings the constructor property returns function String() { [native code] }
