如何使用键将数组转换为多个对象？

Question

I'm unable to optimize the function to convert an array into multiple objects with keys for my desired output.

const students = [
  ['Name01', 'Sub01', 'y', 'Sub02', 'y', 'Sub03', 'y', 'Sub04', 'y', 'OverAll', 'y', 'SecA'],
  ['Name02', 'Sub01', 'n', 'Sub02', 'y', 'Sub03', 'y', 'Sub04', 'y', 'OverAll', 'n', 'SecA'],
  ['Name03', 'Sub01', 'y', 'Sub02', 'y', 'Sub03', 'n', 'Sub04', 'y', 'OverAll', 'n', 'SecB'],
  ['Name04', 'Sub01', 'y', 'Sub02', 'y', 'Sub03', 'y', 'Sub04', 'y', 'OverAll', 'y', 'SecB'],
  ['Name05', 'Sub01', 'y', 'Sub02', 'y', 'Sub03', 'y', 'Sub04', 'n', 'OverAll', 'n', 'SecB']];

const newArr = students.reduce((a, [A1, A2, A3, A4, A5, A6, A7, A8, A9, A10, A11, Sec]) => {
  a[A1] = { Name: A1, Sub01: A3, Sub02: A5, Sub03: A3, Sub04: A7, Sub05: A9, OverAll: A11, Sec }
  return a;
}, {});

console.log(newArr)

And following is the output result for above code:

{
  Name01: {
    Name: 'Name01', Sub01: 'y', Sub02: 'y', Sub03: 'y', Sub04: 'y', Sub05: 'y', OverAll: 'y', Sec: 'SecA'
  },
  Name02: {
    Name: 'Name02', Sub01: 'n', Sub02: 'y', Sub03: 'n', Sub04: 'y', Sub05: 'y', OverAll: 'n', Sec: 'SecA'
  },
  Name03: {
    Name: 'Name03', Sub01: 'y', Sub02: 'y', Sub03: 'y', Sub04: 'n', Sub05: 'y', OverAll: 'n', Sec: 'SecB'
  },
  Name04: {
    Name: 'Name04', Sub01: 'y', Sub02: 'y', Sub03: 'y', Sub04: 'y', Sub05: 'y', OverAll: 'y', Sec: 'SecB'
  },
  Name05: {
    Name: 'Name05', Sub01: 'y', Sub02: 'y', Sub03: 'y', Sub04: 'y', Sub05: 'n', OverAll: 'n', Sec: 'SecB'
  }
}

I'm trying to optimize the code for desired output result as follows:

{
  Pass: {
    SecA: {
      Name01: { Name: 'Name01', Sub01: 'y', Sub02: 'y', Sub03: 'y', Sub04: 'y', Sub05: 'y' }
    },
    SecB: {
      Name04: { Name: 'Name04', Sub01: 'y', Sub02: 'y', Sub03: 'y', Sub04: 'y', Sub05: 'y' }
    }
  },
  Fail: {
    SecA: {
      Name02: { Name: 'Name02', Sub01: 'n', Sub02: 'y', Sub03: 'n', Sub04: 'y', Sub05: 'y' }
    },
    SecB: {
      Name03: { Name: 'Name03', Sub01: 'y', Sub02: 'y', Sub03: 'y', Sub04: 'n', Sub05: 'y' },
      Name05: { Name: 'Name05', Sub01: 'y', Sub02: 'y', Sub03: 'y', Sub04: 'y', Sub05: 'n' }
    }
  }
}
