New issue 2426 by [email protected]: prototype can be readable after some
tricky steps
http://code.google.com/p/v8/issues/detail?id=2426
Please refer to the code below, the output of car1.prototype and
car2.prototype is different, after some tricky steps.
================================================================
function Car(name)
{
this.Name = name;
}
var car1 = new Car("XXX");
function BatManCar(gunNumber)
{
this.GunNumber = gunNumber;
}
// This is a tricky step, it will makes the prototype of all Cars created
after this step to be exposed.
BatManCar.prototype = Car;
var batManCar = new BatManCar(4);
batManCar.prototype = Car;
var car2 = new Car("YYY");
console.log(car1.prototype); //undefined
console.log(car2.prototype); //[Function: Car]
