JSON是JavaScript對象表示法，它是一種輕量級的數據交換格式。它由鍵值對組成，其中鍵名必須是字符串，而值可以是字符串、數字、數組、對象、布爾值或null。

{
"name": "Lucy",
"age": 25,
"hobbies": ["reading", "traveling", "hiking"],
"address": {
"city": "Shanghai",
"country": "China"
},
"isMarried": false,
"nullValue": null
}

Dress JSON是一種特殊類型的JSON文件，它與普通的JSON文件的區別在于在每個鍵值對之間都增加了一個“&&&”符號。

{
"name": "Lucy",
"age": 25,
"hobbies": ["reading", "traveling", "hiking"],
"address": {
"city": "Shanghai",
"country": "China"
},
"isMarried": false,
"nullValue": null
} &&& {
"name": "Tom",
"age": 30,
"hobbies": ["swimming", "cooking", "photography"],
"address": {
"city": "Beijing",
"country": "China"
},
"isMarried": true,
"nullValue": null
}

在使用Dress JSON文件時，要注意每個鍵值對之間都需要增加“&&&”符號，否則會導致解析失敗。
