JavaScript Object Clone | Deep and Shallow Copy in Hindi | Interview Questions

[@Satyamsingh-fw4mh]

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)

[@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

Thank you so much sir.

[@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]

@@codestepbystep it helped me for todays interview sir....😊😊😊i have watched complete tutorial of mern and it helped me a lot....i hade made notes of your all videos....and while making projects i use it a lot....Sir websockets and tensorflow js if possible...❤️❤️❤️it helped me a lot

[@ravi_pk]

Nice sir

[@talibhusain3335]

Wow💐

[@fatimaiqra2169]

Thanks

[@ehtixhamamjad]

please explain Array.prototype.slice & JSON.parse(JSON.stringify(obj))

[@rehanhaq3564]

This keyword or event loop

[@ChetanPednekar]

Nice example & explanation Anil. Thanks! Just wanted to confirm if we can call (...) three dots as a 'spread' operator instead of 'de-structuring' ?

[@deepakbhardwaj0805]

No

[@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

[@thersh4882]

Wowww
