从 Json Object 中提取嵌套值是否有更好的选择

Question

I extract generically val2 like below, it works, but is there a lighter way?

let myJsonObject = {
    'key1': {'key1.1': 'value1.1'},
}
let val1 = myJsonObject['key1'];
let key = Object.keys(val1)[0];
let val2 = val1[key];

Answer 1

myJsonObject['key1']['key1.1'] gives you the same result, but this by itself doesn't go anywhere.

It would be a lot more interesting and useful for you if you could explain the bigger picture of why you need to read a nested field in your object so that we can discuss about a more general and meaningful solution.

Some info could be where this object comes from and what possible values/formats it can get.
