How to change the value structure specified in an array object by one method is not fixed

let data = [
    {
        id: 1,
        price1: 5,
        price2: 4
    }

let data1 = [
  {
    id: 1,
    price: {
      price1: 6
    }
  }
]

let data2 = [
  {
    id: 1,
    price: {
      price1: {
        price2: 7
      }
    }
  }
]

//  vlaue key

test(data, "price1,price2")
test(data1, "price.price1")
test(data2, "price.price1.pricew")

Why is the structure unstable? In general, this situation is that the design of the data structure is not reasonable.

of course, it may also be because the data sources are scattered, in which case it is better to write an adapter to transform the data structure for each source-- of course, if several array structures change very regularly, you can also use an adapter to solve the problem.
