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.

Kindly make a video on interview questions on cookies , local storage & session storage … also to mention nice explanation on the topics , Thank you 🙏

Great video! Also, a video on local storage, session storage, and Indexed DB with the use case would be a great one.

I didn't find such a great video on Internet !! Thanks, man for such amazing content❤️Keep posting such content !!

Yes, please make some more lectures on interview questions including session and local storage

Yes, please make a video on differences between session storage, local storage and cookies when and how to use them

Yes please make a video on local storage and session storage

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

how well you have explained such complex topics ... great work ....keep it up ..!!!!

100% interview preparation..........very very thankfull...waiting for more such videos.....

Doing great job

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?

Hi Piyush, Thank you for this wonderful series. Please make a tutorial on LocalStorage, Session storage and cookies. Will appreciate it. Thanks!!!

please make a video on How much javascript is enough for interviews and what are the important topics to focus on for interviews

Sir, please make video on session storage and local storage

This video was so life changing, keep up the good work

nice clear explanation , Thanks Sir!

Great Video, Please make video on cookie, session and local storage with examples

Portfolio making please

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

Excellent video as always brother thank you

hi ,,Piyush.. you put great effort for the javascript developers comunity, but you give the example of deep copy of an object is wrong, you just copy the shallow copy of an object, i hope you finds it well and should correct this. And once again i really say thanks for the this type of content;👌👌👍👍

Fellow devs below is a Polyfill for deep copy function deepCopy(obj) { if (typeof obj !== 'object' || obj === null) { return obj; } var copy; if (Array.isArray(obj)) { copy = []; } else { copy = {}; } for(key in obj) { copy[key] = deepCopy(obj[key]) } return copy; }

ThankYou Prabhu ❤❤

Object.assign will create shallow copy not the deep copy if we have nested objects please kindly note this

Yes please make video on localstorage n session n cookies

Awesome

Please make the video on local storage, session storage, cache and cookies etc

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?

awesome ❤❤

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.

Good and specific content.. 👌

Bro!!!!!!!!!!!!!!!Awesome Video

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

You are gor for me.

can you explain about cyclic structures and why we cannot apply json.stringify on them?

kindly make video on localStorage session

Nice Explanation 🔥

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.

You are great ❤

5:38 Trying to loop through an object will NOT work in react. it will give "'key' is not defined"

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

pls make video on storage

Hi all... i have small doubt for the below object...how to find key and value both ("second " : 2) in the below object..please i need your solutions const iem = { "first" : new Date(), "second" : 2, "third" : "test" }

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);
