javascript - 如何从对象创建数组？

Question

我有这个看起来像这样的对象:

let dataObject = {firstName: "Mike", employeeId: "1020"}

我想用每个属性创建一个数组，如下所示:

let newArray =  [
{operator:"sum", value: "Mike", property: "firstName", type: "string"}, 
{operator:"sum", value: "1020", property: "employeeId", type:"string"}
];

到目前为止我得到了这个:

    let dataObject = {firstName: "Mike", employeeId: "1020"}
    let newArray = Object.keys(dataObject).map((key)=>
       `{${key}}:${dataObject[key]}`
    );
    console.log(newArray);

但我仍然无法获取数组中的对象。如何创建这个数组？

Answer 1

let dataObject = {firstName: "Mike", employeeId: "1020"};

var newArr = Object
  .keys(dataObject)
  .map((key) => {
  return { operate: 'sum', value: dataObject[key], property: key, type: typeof dataObject[key]}
});

console.log(newArr);
