1. Objects are copied by reference and variables by value.
2. To copy objects by value:
==>Object.Assign({}, obj)
==>{...obj}
3. The above method is shallow copy. It copies only top-level fields.
4. To copy nested objects, deep copy comes into picture.
==>JSON.parse(JSON.stringyfy(obj));
5. But the above doesn’t copy functions and dates. So, loadash is used.
==>_.cloneDeep(obj)

[@rajnisrivastav1599]

The best explanation one could have asked for. I just have one question what if the Interviewer ask which is better Deep copy or shallow copy?

[@codestepbystep]

They can not ask which one is better. We choose copy type over requirement

[@rehanhaq3564]

This keyword or event loop

[@InspiringPositiveQuotes1196]

helpful brother

[@sanjanaprajapati9707]

Really good explanation 👍

[@azanraja5089]

if we put an console in between like:-
let obj = {
name: "peter",
};
console.log(obj);
let user = obj;
user.name = "hello";
console.log(obj);
than the result is
peter
hello
why it already update the obj value than why the peter prints
why the hello not prints 2 times

[@Nishantsingh-ys5cm]

bro the output is correct because you console.log('obj') before copy it to the user.

[@kamaal2110]

so what then if we have a object and it properties with function and we have to copy it by `let obj2 = Object.assign({}, obj1);` and modified one property value in obj2 so it will be shallow copy or deep copy???

[@shivamtripathi7597]

shallow copy

[@jagdishjena9058]

Thank you so much sir.

[@mohitkumar-zd9pv]

[@travel2react567]

Before watching this video, I was having a lot of confusion about deep copy and Shallow copy but now it's crystal clear. Thanks a lot. Your teaching style is awesome.

[@sudhirmohanty5971]

I have a question regarding shallow copy please explain. U told 8:11 that in shallow copy means value of a object is copied not the reference . But when i search in google there i found inside bracket (In Shallow copy, a copy of the original object is stored and only the reference address is finally copied. ).
please sir clear this to me

[@zeeshanahmad1675]

Rather then going to browser console all the time
Y dont you try { node (name of the JS file) } and press enter
in your vs code terminal
it will be more helpful

[@SajithaKSoman]

Thank you sir . thank you .After a long time , I understand the concept of deep copy and shallow copy from this video.

[@priyeshjammula854]

How can you say solution is not available in javascript Even lodash developers have implemented using javascript only, just that they are providing it as a package. That's misleading

[@VinayTandale]

sir destructing method can be used? let user=[obj] and then we can change both values? is this feasible to use

[@codestepbystep]

destruction will do only shallow copy not deep

[@VinayTandale]
