What are nested data structures and how do they work in different programming languages?

Nested data structures are data structures that contain other data structures. For example, in Python, you can have a list of dictionaries, where each dictionary can hold multiple key-value pairs.

Can you give me an example of nested data structures in JavaScript?

Sure! In JavaScript, you can create a nested object like this: const person = { name: 'John', address: { city: 'New York', zip: '10001' } }; Here, the address is a nested object within the person object.

How do nested data structures differ in Python and Java?

In Python, you can easily create nested lists and dictionaries, while in Java, you typically use classes and objects to achieve similar structures. Java requires more boilerplate code to define these structures.

What are the advantages of using nested data structures?

Nested data structures allow for more complex data organization, making it easier to represent relationships and hierarchies within data. They also enable more efficient data manipulation and retrieval.
