What is JSON?
A lightweight data format that uses human-readable text to store and transmit structured data.
Why It Matters
JSON is the standard data format for web APIs and configuration files, used virtually everywhere in web development.
Real-World Example
An API response like {"name": "Jane", "city": "Melbourne"} is JSON.
“Understanding terms like JSON matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”
