Javascript - The art of accessing an anonymous array

I'm trying to extract data from an API, but I've run into a snag. There's a list without a name attached to it, making it impossible for me to access the values inside. Here's a simplified example of what I mean:

(Here is the JSON structure)

{
"numberOne": [
    {
        (other information would be in here)
    }
]
}

As you can see, number one contains a nested list with "other information" inside. The issue lies in accessing this data using my current JavaScript method - I can't simply call convertedJson.numberOne.?.otherInformationValue.

Does anyone have any suggestions on how to handle a situation like this?

Thank you!

The list mentioned in the example is named numberOne. To retrieve the elements within the list, you can reference them by their index:

exampleJSON = {
    "numberOne": [
        {
            "num1" : "value1"
        },
        {
            "num2" : "value2"
        },
    ]
}

let value1 = exampleJSON.numberOne[0].num1;
let value2 = exampleJSON.numberOne[1].num2;
//...and so on
