What is JSON?

JSON (JavaScript Object Notation) is a lightweight, human-readable data interchange format widely used in web applications and APIs. Its simple structure makes it ideal for transmitting data between servers and web applications.

JSON Example:


                              "name": "John Doe",
                              "age": 30,
                              "city": "New York",
                              "skills": ["JavaScript", "Python", "SQL"]

JSON Advantages:

  • ✓ Lightweight and fast to parse
  • ✓ Human-readable format
  • ✓ Supports nested structures
  • ✓ Language-independent

Common Use Cases:

  • • API responses and requests
  • • Configuration files
  • • Data storage and transmission
  • • NoSQL database documents
