My bad in my haste to assist I missed some other things with your code. I commented them in the code below. https://code.sololearn.com/Wza4BQ2ITA98

From the API documentation: "Quickstart - Get a random Kitty Using the language / framework of your choice: Load https://api.thecatapi.com/v1/images/search Get the first Array object of the JSON response Load itā€™s .url Enjoy the kitty šŸ˜ŗ Bonus: Add a button to repeat the request for a new kitty!" (https://docs.thecatapi.com/) The important part for your last question is "Get the first Array object..." therefore you have to use 0 as index. It's just the way the data is structured in the json. Every API should come with documentation of some kind. When none is available you have to look at the file and figure out the structure yourself.

We're talking about the brackets at the start. // initial array (data) [ // object is the first element of the array at data[0] { // properties of the object "breeds":[], "categories":[{"id":7,"name":"ties"}], "id":"u1", "url":"https://cdn2.thecatapi.com/images/u1.jpg",// data[0].url "width":625, "height":446 } ]

data[0] gives you the braces and everything between (breeds to height).

Your Mom data ----> [{ ... }] <-array array is accessed by index data[0] ----> { ... } <-object object is accessed by key data[0].url ----> "https....jpg" examine what the api returns and process them appropriately. fun apišŸ˜ https://code.sololearn.com/W4wFF883v1V2/?ref=app

I do not know. Is that what you got when you searched it up? If so, it may be best to use a different API.

For me it is definitely saying something. It says the error one you press the New Cat button.

Always make sure to check the console when you're not getting exactly what you want. You're getting an accessed blocked error. You can type the error into Google and you might be able to find what the problem is.

In your js code showNewCat(url) it requires an URL, but in HTML an url is not passed to showNewCat() when the button is clicked. Why?

Yes I see that and that url will be used for that call to the function and when the function is done that instance of the function is thrown away. When you press the button you are invoking a new instance of showNewCat function and it need an url also.

The quick fix is to pass the url via the onclick attribute onclick="showNewCat('https://api.thecatapi.com/v1/images/search')"

The API returns an array with one element and array indexes start with 0. This means that the array's first and only element has an index of 0. Hence data[0]. If I were to use data[3] or data[1], undefined would be returned. https://www.w3schools.com/js/js_arrays.asp
