I tried to request data from this server address `https://codexpression.github.io/catz/catz.json ` using AJAX XMLHttpRequest, but when I tried to `console.log` the property value of the text, I keep getting “undefined”, please find code below

```auto
function getData() {
  let requestObject = new XMLHttpRequest(); //create XMLHttpRequest Object

  requestObject.onreadystatechange = function() { //create an onstatechange function
    if (this.readyState == 4 && this.status == 200) { //check if request is successful
      // myFunction(this)
      let convert = JSON.parse(this.responseText)
      console.log(convert.all.text)
    }
  };

  requestObject.open("GET", "https://codexpression.github.io/catz/catz.json", true); //get the document address and send request
  requestObject.send()
}

getData()

```

I am not in front of my computer to check, but what does just `this.responseText` print? Does it display a large blob of data?

I think it worked  
it returns the below

1. {results: Array(1), info: {…}}

2. info: {seed: “0d23199c55f504d6”, results: 1, page: 1, version: “1.3”}

3. results: Array(1)

```
1. 0: {gender: "female", name: {…}, location: {…}, email: "kelya.perez@example.com", login: {…}, …}
2. length: 1
3. __proto__ : Array(0)

```

1. **proto** : Object

It did seem to return an array of data! 🙂

thank you, so I need to use array methods i.e index notation instead of the dot notation, thanks it worked

It all depends on how the data gets returned. You’ll have to inspect the raw data returned and figure out the right next step from there 🥳

Oftentimes, the API documentation can be helpful as well.
