Chapter 3 — Using JSON in Applications
Because JSON is platform-independent and widely supported, it is commonly used to exchange data between different systems. Databases, web services, and applications often rely on JSON to transmit structured information efficiently.
Example: Data exchange
{
"transaction": {
"id": "TX1001",
"amount": 49.90,
"currency": "USD"
}
}This structure could represent a transaction shared between financial systems.
