setting object key dynamically in javascript

Suppose I have an object like this :

let inputData = {
  "dimensions": [
    {
      "id": "dimension_re",
      "label": "Region",
      "values": ["East", "East", "West", "SouthWest", "South","NorthEast"]
    }, 
    {
      "id": "dimension_cnt",
      "label": "County",
      "values": ["London", "Italy", "Germany", "US", "Russia","India"]
    },
    {
      "id": "measure_sales",
      "label": "Sales",
      "values": [100, 156, 432, 462, 25,100]
    }, 
    {
      "id": "measure_qty",
      "label": "Quantity",
      "values": [85, 34, 153, 434, 52, 43]
    }, 
    {
      "id": "measure_profit",
      "label": "Profit",
      "values": [123, 45, 421, 465, 451, 56]
    }
  ]
}

Now my expected output would be this:

let expectdData = [
  {
    "Region": "East",
    "County": "London",
    "Sales": 100,
    "Quantity": 85,
    "Profit": 123
  }, 
  {
    "Region": "East",
    "County": "Italy",
    "Sales": 156,
    "Quantity": 34,
    "Profit": 45
  }, 
  {
    "Region": "West",
    "County": "Germany",
    "Sales": 432,
    "Quantity": 153,
    "Profit": 421
  }, 
  {
    "Region": "SouthWest",
    "County": "US",
    "Sales": 462,
    "Quantity": 434,
    "Profit": 465
  }, 
  {
    "Region": "South",
    "County": "Russia",
    "Sales": 25,
    "Quantity": 52,
    "Profit": 451
  },
  {
    "Region": "NorthEast",
    "County": "India",
    "Sales": 100,
    "Quantity": 43,
    "Profit": 56
  }
]

So here is my Program to get this expected data:

let actualData = [];

inputData.dimensions.forEach((e,i) => {
  let tempVal = e.label;
  e.values.forEach((elem,index) => {
    actualData[index] = new Object({
      [tempVal] : elem
    });
  })
});

console.log(actualData);

But unfortunately, I only get the last item for every object. In my console it looks like this:

[
  { Profit: 123 },
  { Profit: 45 },
  { Profit: 421 },
  { Profit: 465 },
  { Profit: 451 },
  { Profit: 56 }
]

I think, in every iteration, it just overrides the "tempVal" variable. How to prevent this & how can I achieve the expected array of objects? Kindly let me know.

>Solution :

You are replacing the whole object on each iteration, you just need to create it if it does not exists, otherwise you can replace the key.

let actualData = [];

inputData.dimensions.forEach((e,i)=>{
  let tempVal = e.label;
  e.values.forEach((elem,index) => {
    if (!actualData[index]) {
      actualData[index] = {}
    }
    actualData[index][tempVal] = elem
  })
});

console.log(actualData);
