function changeStuff(num, obj1, obj2){ num = num * 10; obj1.item = "changed"; obj2 = {item: "changed"};}var num = 10;var obj1 = {item: "unchanged"};var obj2 = {item: "unchanged"};changeStuff(num, obj1, obj2);console.log(num); // 10console.log(obj1.item); // changedconsole.log(obj2.item); // unchanged為什么是這個情況？
