限定key,输出去重后的数组，期望数组如下；

求:限定key,输出去重后的数组，期望数组如下；

已经知道数据集:
const data = [
{name:'A',age:17},
{name:'B',age:18},
{name:'C',age:19},
{name:'B',age:18},
{name:'C',age:19},
]

keys_list = ['A','C']

求:限定key,输出去重后的数组，期望数组如下；

result = [
{name:'A',age:17},
{name:'C',age:19}
]




function handleCookies(cookiesObj) {
    var _cookeis = ''
    let res = []
    const keys_list =  ['A','C']
    for (let i in cookiesObj) {
        const name = cookiesObj[i].name;
        console.log(name,'name')
        if (keys_list.includes(name) && (res.includes(name) === false)) {
            const age = cookiesObj[i].age
            _cookeis += cookiesObj[i].name + '=' + cookiesObj[i].age + ';';
        }
        res.push(name)
    }
    console.log('_cookies', _cookeis);
}

handleCookies(data)
