函数参数“item”属性的赋值

Question

我有那个lint错误：赋值到函数参数“项目”的属性

删除此错误的正确方法是什么？

const resp = await getData(payload)
resp.forEach((item) => {
      item[0] = moment(item[0]).format('DD/MMM/YY');
});

Answer 1

下面是一个使用map的示例。

js prettyprint-override">const response = [ [ "07/10/2020", 0.04, 0.05, 0.04 ], [ "07/10/2020", 0.04, 0.06, 0.04 ] ];

// Iterate over the response
const data = response.map(item => {

  // For each item destrucuture the data from
  // the rest of the elements
  const [date, ...rest] = item;

  // Return a new array which has the updated
  // date, and the other elements then spread out
  return [
    moment(new Date(date)).format('DD/MMM/YY'),
    ...rest
  ];

});

console.log(data);
