如何制作可以访问对象项的自定义函数？ [复制]

Question

想知道我们如何在传递给函数时访问对象中的项目：

const sortArrayObj = (arrayObj, field) => {
  //How to access "arrayObj[0].field" ???
  // Tried to do console.log(`${arrayObj[0]}`) and it gave output as [Object object]
  //Now how can i access "name" and "date" from it using the "field" variable ?

};

const arr = [
  { name: "A", date: "13-12-1996" },
  { name: "G", date: "03-02-2020" },
  { name: "C", date: "09-05-2021" },
];
sortArrayObj(arr,"date")

尝试以下方式：

const sortArrayObj = (arrayObj, field) => {
  // How to access "arrayObj[0].field" ???
  arrayObj[0][field];
};
