Previous console log change after assign new value in javascript sub object property. Help me

Question

Recently I am facing problem with javascript sub object value assign. My sample code is

var user = {
        name: {
            fname: 'Apple'
        }
    };

console.log(user);
user.name.fname = 'Orange';
console.log(user);

So its console twice But, fname value always show Orange. But I want output will be Apple then Orange. How do i do that or actually what happened? Please Let me explain actually what going on.

Try this code:

var user = {
        name: {
            fname: 'Apple'
        }
    };

console.log(user.name.fname);
user.name.fname = 'Orange';
console.log(user.name.fname);

Cheers.

You can use console.dir(object) to print object

console.dir(user);

Don't need to use console.log(user.name.f);
