What is JSON?

JSON stands for JavaScript Object Notation. It is a lightweight text format used to represent structured data.

Why JSON matters

Developers use JSON for API responses, configuration files, logging, and data exchange between systems.

Common JSON structures

• Objects with key-value pairs
• Arrays with ordered values
• Strings, numbers, booleans, and null

When to use JSON tools

A formatter helps with readability. A validator catches syntax errors. A JSON to TypeScript tool helps convert sample payloads into types.

Final takeaway

If you work with APIs or web applications, understanding JSON is essential.
