使用json对象转化为key,value的对象数组

const metaData = {"api-type": "apiparser", "management.port": "8101"}
Object.entries(metaData).map(([key, value]) => ({
	key, value
}))

arr.reduce((acc, curr) => {
  acc[curr.key] = curr.value
  return acc
}, {})

/**
 * 传入对象得到 key、value 形式的对象数组
 * key、value可以自定义
 * @param {Object} MAP 要处理的对象
 * @param {String} key 对象的key
 * @param {String} value 对象的value
 * @returns 数组
 */
export function mapToJson(MAP, key, value) {
  return Object.keys(MAP).map(item => ({
    [key]: item,
    [value]: MAP[item],
  }))
}

var jsonData = {};
var arr = [[1, 'boy', 'dabing'], [2, 'girl', 'dabing']];
for (var i = 0; i < arr.length; i++) {
    var key = arr[i][1];
    var value = arr[i][2];
    
    jsonData[key] = value;
}
console.log(jsonData['boy'])// 'dabing'
