Unable to fetch the data in JSON when a parameter is "integer" in Angular 11

Issue

I have a response for Angular 11 TypeScript code like:

{
  "Id": "12345",
  "length": [
    {
      "a": {
        "1": {
          "test": [
            {
              "days": "20"
            }
          ]
        }
      }
    }
  ]
}

It is unable to fetch data as one parameter is "1". It’s giving a compilation issue when trying to print the value of days like:

console.log(length[0].a.1.test[0].days);

If it’s "one" instead of "1" it’s working fine:

console.log(length[0].a.one.test[0].days);

Solution

Try this working solution. It should work now.

const data = {
  "Id": "12345",
  "length": [
    {
      "a": {
        "1": {
          "test": [
            {
              "days": "20"
            }
          ]
        }
      }
    }
  ]
}


console.log(data.length[0].a[1].test[0].days) // returns "20"
