这个JSON结构是数组还是对象？

Question

我尝试使用JavaScript解析JSON，但我无法弄清楚如何迭代此结构，因为我无法确定这是一个数组，一个对象还是一个对象包含一个数组。这是代码：

{
"noun":
    {
    "syn":
    ["trial","trial run","tryout","mental test","mental testing","psychometric        
    test","examination","exam","run","attempt","communicating","communication","cover","covering","effort","endeavor","endeavour","experiment","experimentation","mental measurement","natural covering","try"]
    },
"verb":
    {
    "syn":["prove","try","try out","examine","essay","screen","quiz","ascertain","be","check","determine","evaluate","find out","judge","learn","pass judgment","score","see","submit","take","undergo","watch"]
    }
}

Answer 1

{}表示JSON块是OBJECT。它有两个属性：noun和verb。每个属性都有一个名为syn的属性，它是一个数组（由[]表示）。
