var a = 1;
var b = a;
a = 3;
console.log("a = " + a);
console.log("b = " + b);
var objA = {
"name": "abc",
"age": 100
};
var objB = objA;
objA.age = 200;
console.log("objA.age = " + objA.age);
console.log("objB.age = " + objB.age);

function Person() {
this.color = ["yellow", "white"];
}
function SubPerson() {
}
SubPerson.prototype = new Person();
var male = new SubPerson();
console.log("male.color = " + male.color);
male.color.push("black");
var female = new SubPerson();
console.log("female.color = " + female.color);
不多說，慢慢體會
