后台传递回来的数组我想转换为另一个数组形式方便我渲染怎么实现呢？

Question

后台给的数据如下

               let arr =[
                    {id:1,name:"小明",value:15,code:"a1a5a5"},
                    {id:2,name:"大明",value:25,code:"a5d5sa51"},
                    {id:3,name:"小红",value:252,code:"bv1c52b"},
                    {id:4,name:"大红",value:225,code:"wq4e5q"},
                    {id:5,name:"小强",value:54,code:"p1i2uo1"},
                    {id:6,name:"大强",value:205,code:"xcz21c"}
                ]

我想要的数据就是把第一个的和第两个的放在一个对象里面方便我循环渲染（就是把小明，大明的放在一起）
我想要的数据格式

          let mydata = [
                    {id:1,name:"小明",value:15,code:"a1a5a5",idTwo:2,nameTwo:"大明",valueTwo:25,codeTwo:"a5d5sa51"},
                    {id:3,name:"小红",value:252,code:"bv1c52b",idTwo:4,nameTwo:"大红",valueTwo:252,codeTwo:"wq4e5q"},
                    {id:5,name:"小强",value:54,code:"p1i2uo1",idTwo:6,nameTwo:"大强",valueTwo:205,codeTwo:"wq4e5q"}
                ]

怎么实现呢？

  const mergeArr = arr => arr.reduce((res, val, i) => {
    if (i % 2) {
      const obj = res.pop()
      for (const [key, value] of Object.entries(val)) {
        obj[key + 'Two'] = value
      }
      res.push(obj)
    } else {
      res.push(val)
    }
    return res
  }, [])
  console.log(mergeArr(arr))
