In this video, I have explained in detail, how to copy
javascript object and what is shallow and deep copy in javascript
Shallow copy is also identified by pass by Reference , when you
make a copy of original variable into another variable(copied) by using
assignment operator(=), that time only the reference address
of original variable is copied into another variable instead of original
values.
So at last both variables refer to the same value. So when you make any changes in
new variable if will also mutate or change the original variable
Deep Copy:
Deep copy is also identified by pass by Value, when you make a copy of
variable into another variable by using assignment operator, at that time
all the values(object, arrays) along with reference address of original variable
is copied into another variable.
At last, both variables refer to different referenced
values. So when you make any change in new variable it won't mutate the original variable.

I have one assignment at the end of the tutorial.

Nicely explained..understand the concept well..just a confusion, Object.assign() is giving partial deep copy, JSON.stringify() also giving partial deep copy...and use of spread operator is giving complete deep copy...so my question is which method is giving shallow copy...is shallow copy same as just assigning one object to another object or something else?

@kalpeshdashpute9598 Жыл бұрын

referance data types like array and object have a by default shallow copy nature

With the help of this JSON.parse(JSON.stringify(object)); you can easily achieve the deep copy

@apurvakumar5881 3 жыл бұрын

i can able to do foe nested and simple objects FOR EX----- var obj = [{ x: 1 }, {y: 2}]; var deepCopy = _.cloneDeep(obj); // Changing orignal value obj[0].x = 10; // Values after changing original value console.log("After changing original value"); console.log("Original value ", obj); console.log("Deep Copy value ", deepCopy); OUTPUT Original value [ { x: 10 }, { y: 2 } ] Deep Copy value [ { x: 1 }, { y: 2 } ]

Good but you are using loadsh methods for it, she did it by using inbuilt es6 features
