JSON files

JSON stands for "JavaScript Object Notation", which is a popular lightweight textual format that is used to store object-oriented data in a human-readable form. It comes from JavaScript where it is the native format used to store object information; however, it is commonly used across many programming languages and a popular format for web data exchange. Qt Core supports JSON format, as we'll see in the following code. A simple JSON-formatted definition looks as follows:

{
    "name": "Joe",
    "age": 14,
    "inventory": [
        { "type": "gold", "amount": "144000" },
        { "type": "short_sword", "material": "iron" }
    ]
}

Type	Description
