for object.assign alwways keep in mind that key must be different otherwise it will overwrite the value
for eg :
const obj1 = {
name: "sandeep",
age: 30
}
const obj2 = {
name: "mandeep",
age: 40
}
const obj3 = Object.assign({}, obj1, obj2);
console.log(obj3);
// output will be
{name :'mandeep' , age :40 }
00:02 In this video, we will talk about creating singletons and constructors in JavaScript objects.

17:40 Understanding big objects in JavaScript
That's good sir🎉🎉❤ after completing pw skill lecture this is literally very helpful
Sir iss se pehle wala lecture Symbol and this keyword and square notations as well as using double quotes for key names it was really out of the box. Bohot bohot dhanyavaad sir
I am watching this playlist from Pakistan and your teaching way is Amazing ❤❤❤ God bless you
hey bro so now 12 months later what are you doing right now job , clg , internship or what please guid me !!!!!!!!!!
I would like to share my observation as well...
let Obj1 = { 1: "a", 2: "b" };
let Obj2 = { 3: "c", 4: "d" };
let Obj3 = { ...Obj1, ...Obj2 }; //Here I have used spread operator but in order to access I need to use []
let Obj4 = Object.assign({}, Obj1, Obj2); //Best practice beacause it would not change the source object (Obj1)
//let Obj4 = Object.assign(Obj1, Obj2); //Bad practice
console.log(Obj1); //It make changes in target Object as well.
Thanks a ton sir!

@adityadomle1 Job.
Try to get a job and then learn on the go. That's all my advice would be.
@@tarunsoni2443 thankS bro ... Btw can I add you on my LinkedIn
"Excellent explanation of objects in JavaScript, with clear examples and real-world application. Highly recommended!" #javascript #chai
One of the best free resource on Yt without any doubt
const obj1 = {a:1}
const obj2 = {b:2}
const obj3 = Object.assign([],obj1,obj2)
console.log(obj3)
[1, 2]

Best series for learning js sir I appreciate you very much.
really best javascript eries keep going on sir you are the one of the best teacher in my life
Best series of js ❤
SUMMARY :
1.To declare singleton object => new Object( );
2. To merge object use spread operartor. {...Obj1, ...Obj2 } or
Object.assign( { }, obj1,obj2 ):
3. To return keys from object => Object.keys(object name);
4.To return values from object => Object.values(object name);
5.To check property of object => Object.hasOwnProperty(key/value name);
Seriously sir ,ur way of teaching technique is just drop dead gorgeous 🥰💞
just Loving this playlist ❤
best javascript tutorial ❤

best teacher till now
at 8:19 is it correct
const obj1 = {1:"a",2:"b"}
const obj2 = {3:"a", 4:"b"}
const obj3 = {...obj1,...obj2}
console.log(obj3)
This could have took me a whole year to understand until discovering your playlist❤❤🙏
best javascript course ever made 🔥
world class series of javascript
Giving an Empty object as a target will not modify the value of obj1 , if we donot give the empty object as target then It will consider Obj1 as target and the value of Obj1 will be modified.
Hitesh Bhai you are awesome ❤
absolutely mind blowing video ..just love it
Asli Gyaan Yahan milta hai 💥
Amazing and indepth series.

So addictive ❤
Fantastic video...great learning
Literally learn new concept here....
Best Teacher of JS❤
it's just really unbelievable. Thanks mentor
i think at 10:30 obj3=Object.assign({},obj1,obj2) create new space for obj3 so change in obj3 dont make any change in obj1. but in (obj1,obj2) make obj3 and obj1 connected
Hanjiiiiii maja aaa raha hai series ko complete karna ka
I don't have words to say about this series I'm so addicted
@hitesh sir isko spread operator bi assign kr skte the hum to assign ku kiya ye doubt h mera
Thank you so much sir ❤
one of the best javscript playlist.
object.assign or destructuring which is good approach
Sir your teaching skills are awesome!!Thanks so much for this tutorial!!
now i know objects really well
sir ager two object ki same key rhegi to third object mei spread karte time vo sirf second wale ko print karega kyu ki object2 first object ko overwrite kar dega to sir iss case mei to spread use nhi kiya jaa sakta
In Privious and this video dono me ek hi tarike se object declare Kiya hai to different kaise hua (singleton kaise hua)? Please help
Just awesome, maja aa gaya
thank you sirr🙏🙏🙏🙏🙏🙏🙏🙏🙏
Best Object video
sir kya hum array me jo flat(infinity) use kiye the vo object k elements k liye use kr skte he . instade of
(regulurUser.fullname.userfullname) . i tryed but not work .
Hello Bhai, agr hm array ke inside multiple object create krte with key 0,1,2 etc. to ese hm kese access krnege esme
One of the best
Please correct me if I'm wrong you said object created using constructor are objects literal but in Google it's says object created by object literals are singleton I'm confused
Teaching style man 🔥❤
weren't we supposed to initialize const variables?
Sir, const obj1= new Object(); is not a Singleton object
At 13:00 you are actually accessing second object from array if you write user[1]
me bi yahi bolne wala tha
Sir your playlist is Supercalifragilisticexpialidocious!!!!!
❤️❤️
you are providing the realtime content which will surely use in our projects when we will get in any company, not only the bookish knowledge but the things from your own experience. this is great bhai. you are pure gem of teaching. i never see this type of content anywhere , this is the best tutorial someone can ever have. Thank you so much .
Great job
Can anyone explain how const tinder = new Object() is a Singleton and const tinder = {} is not? Because when I was checking it on gpt for more clarfication, its saying that "neither const tinder = new Object() nor const tinder = {} creates a singleton object. Both are just different ways to create a new object instance".
best series blessings from pakistan
you are super awsm!!
Thank you sir for this amazing Tutorial
9:23 there were two b , b:2 and b:4 but in expected output only b:4 is mentioned where is b:2 ?
may be it took greater value variable
Thank You Hitesh Sir!
Sir, mujhe logic building sikhna hai but sikh nahi pa raha hu kyu ki koi video me samjh hi nahi a rha hai kkse structure banau kaise logic plant samjh nahi ata or product level par koi project sikhao sir, sath me interview bhi nikal jaye
Bhaiya in video 8:30 You're explaining how to merging two objects but the same thing I am doing in my Laptop I am getting different output
const obj1 = {number: '1', isThere: true, name: 'sphix'};
const obj2 = {number: '2', isThere: false, name: 'canopus'};
const obj3 = Object.assign({}, obj1, obj2);
console.log(obj3);
Output { number: '2', isThere: false, name: 'canopus' }
While I search the issue on CHATGPT, It's telling that It's Overwriting the values
**********************CHAT GPT Response********************************************
The `Object.assign()` method in JavaScript is used to copy the values of all enumerable properties from one or more source objects to a target object. In your case, you are creating a new object (`obj3`) by merging the properties of `obj1` and `obj2` into an empty object `{}`.
The reason you are not seeing the properties of `obj1` in the result is because the properties of `obj2` are overwriting the properties of `obj1` during the assignment. The `Object.assign()` method assigns values from right to left, so the properties of `obj2` overwrite the corresponding properties of `obj1` in the new object.
If you want to include the properties of both `obj1` and `obj2` in the resulting object, you can swap the order of the objects in the `Object.assign()` method:
```javascript
let obj3 = Object.assign({}, obj2, obj1);
console.log(obj3);
```
Now, the properties of `obj1` will overwrite the properties of `obj2` in the resulting object. Keep in mind that if there are overlapping properties with different values, the values from the object on the right will take precedence.
I got my mistake when I watch ahead. My Bad Sorry Sir

I don't have words to say about this series I'm so addicted . Before this series i hate javascript I don't want to learn but now i am waiting for new video please post new video as soon as possible thank you sir you are doing great work 💯❤
If the keys of both objects are the same, the spread operator is producing unexpected output.
this keyword kise use kare arrow function ke sath ?
hy sir hope u doing well
why this happens ?
const obj1 = {a:1}
const obj2 = {a:2}
const spread = {...obj1, ...obj2}
console.log(spread, "from spread");
and the answer is____ { a: 2 } from spread
why { a: 2 } not {a : 1 }
because both object has same property name so spread will overide the value of last object..
ek number
Thank you Sir
Thank you sir ❤❤
I think you missed constructor
And how singleton is object is created can you explain in detail
love this tutorial 😍😍😍😍😍
Awesome!!
