Interview Questions

[Satyamsingh-fwmh]

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.



5. But the above doesn’t copy functions and dates. So, loadash is used.

==>_.cloneDeep(obj)
