如何将部分json响应转换为map

Question

我有JSON响应，看起来像这样

{"values": 
 [
        {
            "type": "NAME",
            "match": "EXACT",
            more properties here
        },
        {
            "type": "LASTNAME",
            "match": "AMBIG",
            more properties here
        }
] }

如何将此转换为仅包含类型和匹配属性的javascript地图？

例如

{
 'NAME' : 'EXACT' ,
 'LASTNAME' : 'AMBIG' 
}

这是我的尝试：http://jsfiddle.net/u9ycpLgs/

循环遍历test.values并创建一个新对象，其中type的值是新键，匹配的值是新值。

var test = {
    "values": [{
        "type": "NAME",
            "match": "EXACT"
    }, {
        "type": "LASTNAME",
            "match": "AMBIG"
    }]
};

keyValuePairs = {};

test.values.forEach(function (item) {
    keyValuePairs[item.type] = item.match;
});


console.log(JSON.stringify(keyValuePairs));

/*
 Output:

  {"NAME":"EXACT","LASTNAME":"AMBIG"}
*/
