How to find dynamically a key values inside an object?

Question

each API request I'm making contains different keys values inside a specific object. How can I dynamically get the Number value of the second key? ("123112042")

"salesRanks": {
    "281052": [ keepaTime, salesRank, ... ]
    "123112042": [ keepaTime, salesRank, ... ]
}

Answer 1

Target the Object.keys and get the second index.

const data = {
  salesRanks: {
    "281052": [1, 1],
    "123112042": [2, 2]
  }
};

console.log(Object.keys(data.salesRanks)[1]);
