Is there a way to effectively eliminate an array of objects in JavaScript or TypeScript and alter the object structure simultaneously?

I am seeking solutions to restructure an object that has multiple arrays of objects so that I can access the object directly.

console.log(value.data.summary[0].data)

Instead of accessing arrays in this manner, I want to modify my data structure. Is there a way to create an object similar to the 'result' object where nested array of objects can be accessed directly?

I aim to establish a result object that allows for direct access to the nested array of objects.

  let value =   {
   "data":{
      "summary":[
         {
            "code":"9280",
            "data":[
               {
                  "val1":"test1",
                  "val2":"CAD",
                  "val3":0,
               },
               {
                  "val1":"test2",
                  "val2":"USD",
                  "val3":0,
               },
            ]
         },
      ]
   }
}

  let result =   {
   "data": {
      "code":"9280",
      "summary":[
               {
                  "val1":"test1",
                  "val2":"CAD",
                  "val3":0,
               },
               {
                  "val1":"test2",
                  "val2":"USD",
                  "val3":0,
               },
            
         
      ]
   }
}

If you're looking to update the value to reflect the result, here's a method you can use:

  let value =   {
   "data":{
      "summary":[
         {
            "code":"9280",
            "data":[
               {
                  "val1":"test1",
                  "val2":"CAD",
                  "val3":0,
               },
               {
                  "val1":"test2",
                  "val2":"USD",
                  "val3":0,
               },
            ]
         },
      ]
   }
}
let result =  {data:{
  code:value.data.summary[0].code,
  summary:[...value.data.summary[0].data]}};
console.log(result);

One way to organize the objects in the data array is by assigning them a key:

let value = {
  "data":{
    "summary":[
      {
        "code":"9280",
        "data":{
          0: {
              "val1":"test1",
              "val2":"CAD",
              "val3":0,
            },
          "sum2": {
            "val1":"test2",
            "val2":"USD",
            "val3":0,
          },
        }
      },
    ]
  }
}

Consider applying a similar key organization to the summary array, or consolidating it into one object for better structure.

// Summary with keys
let value = {
  "data":{
    "summary": {
      "sum1": {
        "code":"9280",
        "data":{
          0: {
              "val1":"test1",
              "val2":"CAD",
              "val3":0,
            },
          1: {
            "val1":"test2",
            "val2":"USD",
            "val3":0,
          }
        }
      }
    }
  }
}

// Summary as a single object
let value = {
  "data":{
    "summary": {
      "code":"9280",
      "data":{
        0: {
            "val1":"test1",
            "val2":"CAD",
            "val3":0,
          },
        "example": {
          "val1":"test2",
          "val2":"USD",
          "val3":0,
        }
    }
  }
}
