将一个对象属性拆成两个个对象放到数组中？

Question

const obj = { 0: '男', 1:'女'}
function f(obj) {
  // 写代码
}
const arr = f(obj) // arr ===>  [{label: '男', value: 0},{label: '女', value: 1}]

Answer 1

const obj = { 0: '男', 1:'女'};
Object.entries(obj).map(([value,label])=>({label,value}));
//[{label: "男", value: "0"},{label: "女", value: "1"}]

Answer 2

遍历对象属性，push到一个新数组就OK了

function SplitA(object) {
    if (object.constructor !== Object) return null
    const arr = []
    for (const key in object) {
      if (Object.hasOwnProperty.call(object, key)) {
        const newObj = {}
        newObj['label'] = object[key]
        newObj['value'] = key
        arr.push(newObj)
      }
    }
    return arr
  }

Answer 3

function f(obj) {
                return Object.keys(obj).reduce((result, key) => {
                    result.push({label: obj[key], value: key});
                    return result;
                }, [])
            }
