Amazing!! Everyone say that an object is referred to by a memory address but no one showed it. You are showing it and also how it is happening in browser.
Now this makes more sense and also easy to remember.
And @40.00 you showed how one object is stored in another object, that blew my mind, it was so simple.
Thanks for sharing the knowledge.

Thank you so much, Sir, for sharing your excellent knowledge with us. Every day, I watch 5-6 of your JavaScript videos and practice regularly. A few days ago, I was looking for the best JavaScript tutorials on YouTube and luckily found your channel. Once again, thank you so much. I hope one day I will become a good developer.

const user1 = {

lastName: 'Sharma',
pata : {
city: 'Delhi',
pincode: 123456
},
subject: ['CS', 'DS', 'CN']
}

const user2 =

By using Json we can make deepcopy let's understand through an example:

const ingredientsList = ["noodles", { list: ["eggs", "flour", "water"] }];
const ingredientsListDeepCopy =

JSON.stringf() converts the original element of an array into strings and then JSON.parse converts the strings elements into Object / Array by doing this the address of original array will change and this time we'll get deep copy of previous object / Array not shallow copy.

may be I'm not able to make more clear to you. For more clarity you can see mdn.

As it seen in the snapshot even the address of the immediate key-value pair such as firstName and lastName have the same address in both the objects but changing one of them is not reflecting in the other one(in Shallow copying). Can someone explain it ?

[henilkakadiya]

using 1) name)) 2)structuredClone(variable name)

[sahajranipa]

If we can assign an array to another array like objects using the assign() method can we use the same method for functions if yes what the use cases??
