vue 数组去重

test() {
      const arr =[
        {
          name: '张三',
          age: 22},
        {
          name: '李四',
          age: 22},
        {
          name: '张三',
          age: 23}
      ]
      const map = newMap()
      const qc = arr.filter(key => !map.has(key.name) && map.set(key.name, 1)) //这里对name属性进行去重
      console.log('qc')
      console.log(qc)
    }
