参考数据类型与JavaScript中的原始数据类型进行比较

Question

I am a little bit confused about this topic for example

var person = "Kobe";
var another = person;

is variable another create an another copy or just reference to person? That being said, if I change person to something else, will another also be changed??

Compare to

var person = {name: "Kobe"};
var another = person;

Thanks for the help
