Objects & Nested Structures

JSON objects are collections of key-value pairs, and they can be nested to represent complex data structures.

Object Basics

Objects use curly braces {} and contain key-value pairs:

{
  "key": "value",
  "anotherKey": 123
}

Nested Objects

Objects can contain other objects, creating hierarchical structures:

Real-World Example: User Profile

Exercise: Access Nested Data

Exercise: Extract Nested Object

Key Points

• Objects can be nested to any depth
• Use dot notation to navigate: obj.prop.nested
• Complex data is often deeply nested
• Plan your data structure for easy access
