vue3在setup中如何将数组变为数组对象并且对象中的值为该数组的每项值并且每个对象中增加一个属性和值

可以使用map函数将数组转化为数组对象,并在每个对象中增加属性和值,示例代码如下:
```
const arr = [1, 2, 3, 4];
const arrObjects = arr.map(item => ({ value: item, extraProperty: 'extraValue' }));
console.log(arrObjects);
// Output: [{ value: 1, extraProperty: 'extraValue' }, { value: 2, extraProperty: 'extraValue' }, { value: 3, extraProperty: 'extraValue' }, { value: 4, extraProperty: 'extraValue' }]
```
在Vue3的setup函数中,可以这样使用:
```
import { ref } from 'vue';
export default {
setup() {
const arr = [1, 2, 3, 4];
const arrObjects = ref(arr.map(item => ({ value: item, extraProperty: 'extraValue' })));
return {
arrObjects,
};
},
};
```
