ios - 从数组中删除重复数据

Question

我有 2 个数组。

const finalArr = [] 

const arr = ["abc","def"] 
const arr2 = [ 
               { name: "abc", refresh: false },
               { name: "efd", refresh: false },
               { name: "def", refresh: false } 
             ]

现在我正在尝试将 arr2 的刷新值更新为 true 以匹配来自 arr 的名称，它返回重复值:

这是我的代码:

arr2.map(obj => {
      arr.map(name => {

        if (obj.name === name){
          finalArr.push({ ...obj, refresh: true }) 
        } else{
          finalArr.push({ ...obj, refresh: false }) 
        }
      })

谁能告诉我它有什么问题吗？

Answer 1

这很简单:

const finalArray = arr2.map(obj => {
   return { ...obj, refresh: arr.includes(obj.name) };
}
