数组对象中相同属性，属性值合并（拼串）

var Array = [
    {
        "22": "333"
    },
    {
        "555": "444"
    },
    {
        "22": "666"
    }
]
//实现的数组：[{ "22": "333,666"},{"555": "444"}]
var newArr = []
Array.map(value => {
    for (const key in value) {
        newArr.length ? addArr(newArr, value, key) : newArr.push(value)
    }
})

function addArr(newArr, value, key) {
    newArr.map(newVal => {
        if (newVal[key] || newArr.some(item => item.hasOwnProperty(key))) {
            if (newVal[key] && newVal[key] != value[key]) {
                newVal[key] = value[key] + ',' + newVal[key]
            }
        } else {
            newArr.push(value)
        }
    })
    return newArr
}

console.log(newArr)
