JSON

JSON（全名 JavaScript Object Notation）係由 JavaScript 演變出嚟嘅一種檔案格式，常用於網絡嘅數據交流；JSON 會用人類睇得明嘅文字嚟儲同傳達包含一拃拃名-值對同陣列（或者第啲做咗序列化嘅數值）嘅數據物件^[1]。

好似以下噉，就係用 JSON 儲住咗一個人嘅個人資料：

{  "firstName": "John",   "lastName": "Smith",  "isAlive": true,  "age": 27,  "address": {    "streetAddress": "21 2nd Street",    "city": "New York",    "state": "NY",    "postalCode": "10021-3100"  },  "phoneNumbers": [    {      "type": "home",      "number": "212 555-1234"    },    {      "type": "office",      "number": "646 555-4567"    }  ],  "children": [],  "spouse": null}
