For me , a great video for revision. Thanks. Just a minor thing I would like to add for deep and shallow copy. While we use Object.assign({}, obj) or use spread operator {...obj} , only the primitive objects inside the main object gets deep cloned into new object. For the nested objects, only the reference is stored, which is basically shallow copy.

Great video, thank you. For the last question I'm confused, Object.assign and spread operator, do they really create a deep copy? Would have been great if the video ended with the sone nested object examples.

@pratikwadekar4981 2 года назад

JSON.stringify and JSON.parse will only work on JSON safe objects. If the objects contain functions, symbols or dates that won’t create a deep clone

@kmsnymisha4607 2 года назад

Can you please explain why the members array remained same when person is set to null and why it changed to null only on changing the name property in the person object at 21:50

@RoadsideCoder 2 года назад

Because we are reassigning the value which replaces the previous object, but in case of name properly, we are changing the value of that key which has the reference to the original object.

Hi. But we can't reassign to a constant variable. As personObj1 is constant variable then why it is able to reassign in the function changeAgeandName?

@rajathmr4171 16 часов назад

Hey I was watching this tutorial for interview prep, got one doubt this cloning objects with different ways have its own limitiation. Most common is method is not preserved and also complex entities like Set, Map, Regex. loadhash would simpilfy this but how we can do this without using external library is there any Polyfills to it?

@cb559 Год назад

on timestamp 18.10 we are not renaming the value of name , we are assigning the value of name to myName .As renaming means changing the value of name to other string Please correct me if i am wrong

@sidd_shaikh 10 месяцев назад

Hello sir if the object is deeply nested then how can we make deep copy

@floatingcloud5955 Год назад

2:27 fe = function expression You can assign a function() without 'function name' to a variable as value is called Function expression var a= function (){ }

@yaduvanshiNK Год назад

An IIFE (Immediately Invoked Function Expression) is a JavaScript function that runs as soon as it is defined.

@emilyaung2963 2 года назад

Hey wouldn't Object.assign({} , user) and the spread operator do shallow copy? vs the JSON.stringify and parse will do deep copy?

@deepakkolare 2 года назад

Object.assign and spread are shallow copy for nested object for direct properties it’s a deep copy.

@RoadsideCoder 2 года назад

Yes I've mentioned that this doesn't work for nested properties.

Is a career in frontend a good long term option? I feel a career in full stack or backend is better in long term? Your opinion will be helpful on this.

@RoadsideCoder 2 года назад

Yes ofcourse it is! Why would you think that?

@keshavgaur1886 2 года назад

I have been asked about how to print keys i was knowing the concept of foreign loop but don't know what happened during the interview was not able to tell that

@nishantshah_ 2 года назад

Object.assign and destructuring creates shallow copy only.

@bandaumamahesh9346 3 месяца назад

Bro can you please tell me some good books for javascript and react.

How we can compare two objects with same key-value pair but in different order? Also we are not allowed to use Lodash. Only Javascript solution.

@divyasampath2843 Год назад

I did not get this part, if someone can help: Since we are assigning obj1 to obj2, ideally whatever is the value is set to obj1 should be the same for obj2, right? as in, for both, the name should by 'pi', and age 7, isnt it? function change(obj) { obj.name = 'pi', obj = { name: 'hena', age:9, } return obj; } var obj1 = { name: 'div', age: 7, } const obj2 = change(obj1); console.log(obj1); console.log(obj2);
