I just need to retrieve an object by its id from this JSON object (peopleData). When I do typeof peopleData, it returns object. When I try to do typeof peopleData[0] (treating this object as an array because it has brackets as the opening and closing elements) it returns undefined. How do I loop through all of the objects to find the appropriate object if this JSON object is an array that returns "undefined" when I try to get a specific element of that array? I don't know how to enumerate over or de-structure this object since it is an array.

Here are the first few lines from the JSON that I was given (I changed the values but that is irrelevant. I am mainly emphasizing the bracket at the beginning). This is the raw JSON object that I copied from its raw form on GitHub:

[{
    "id": "237856238235",
    "ip_address": "3423423.42.42.4",
    "ssn": "123133231",
    "date_of_birth": "3123123",
    "address": {
        "home": {
            "street_number": "231231",
            "street_name": "ef2ef23",
            "street_suffix": "8i6rth2",
            "city": "wefwdfwef"
            "state": "affwefwfww",
            "zip": "wefsdfbghyj"
        },
        "work": {
            "street_number": "wefgwegwe",
            "street_name": "wefwefwf",
            "street_suffix": "wsfaf",
            "city": "aefaef",
            "state": "afaef",
            "zip": "aefaef"
        }
    }
}, {
    "id": "fwefewf",
    "ip_address": "fwefwf",
    "ssn": "wfwef",
    "date_of_birth": "wefwef",
    "address": {
        "home": {
            "street_number": "efwef",

I have done this before with this exact data and it worked when I just used a small function that cycles through each element of the array, but I have no idea why it is not working now.

You can use filter by the id you want.

const data = [{
    "id": "237856238235",
    "ip_address": "3423423.42.42.4",
    "ssn": "123133231",
    "date_of_birth": "3123123",
    "address": {
      "home": {
        "street_number": "231231",
        "street_name": "ef2ef23",
        "street_suffix": "8i6rth2",
        "city": "wefwdfwef",
        "state": "affwefwfww",
        "zip": "wefsdfbghyj"
      },
      "work": {
        "street_number": "wefgwegwe",
        "street_name": "wefwefwf",
        "street_suffix": "wsfaf",
        "city": "aefaef",
        "state": "afaef",
        "zip": "aefaef"
      }
    }
  },
  {
    "id": "fwefewf",
    "ip_address": "fwefwf",
    "ssn": "wfwef",
    "date_of_birth": "wefwef",
    "address": {
      "home": {
        "street_number": "efwef",
        "street_name": "ef2ef23",
        "street_suffix": "8i6rth2",
        "city": "wefwdfwef",
        "state": "affwefwfww",
        "zip": "wefsdfbghyj"
      },
      "work": {
        "street_number": "wefgwegwe",
        "street_name": "wefwefwf",
        "street_suffix": "wsfaf",
        "city": "aefaef",
        "state": "afaef",
        "zip": "aefaef"
      }
    }
  }]
let result = data.filter(obj => obj.id === "237856238235")
//console.log(result)
console.log(result[0])

I diagnosed my problem incorrectly. It did not have to do with the JSON data. I forgot to use await when getting the data with Axios. Thanks so much for any effort you put in to help me with this.
