- Q1. Javascript object copy, how it works internally
- Ans.
Javascript object copy creates a shallow copy of the object, copying references to nested objects.
Object.assign() can be used to create a shallow copy of an object.
Spread operator (...) can also be used for object copying.
Deep copying requires a custom function to recursively copy nested objects.
- Q2. Higher order function usage
- Ans.
Higher order functions are functions that take other functions as arguments or return functions as results.
Higher order functions can be used to create more flexible and reusable code.
They can be used for tasks like filtering, mapping, and reducing arrays.
Example: Array.prototype.map() is a higher order function that takes a function as an argument to apply to each element in the array.
