What are some examples of nested structures in programming?

Nested structures in programming refer to data structures that contain other data structures. For example, a list of dictionaries in Python is a common nested structure.

Can you give me a specific example in Python?

Sure! Here's an example: students = [{'name': 'Alice', 'grades': [90, 85, 88]}, {'name': 'Bob', 'grades': [78, 82, 80]}]. This is a list of dictionaries, where each dictionary contains a name and a list of grades.

What about in JavaScript?

In JavaScript, you can have nested objects like this: const student = { name: 'Alice', grades: [90, 85, 88] };. Here, grades is an array nested within the student object.

Are there any performance considerations with nested structures?

Yes, nested structures can lead to increased complexity and may affect performance, especially with deep nesting. It's important to balance readability and efficiency.
