<!-- Exercise 3: Dog photo gallery
2+
Let's make a randomized dog photo gallery!
3+
Write a function that makes an API call to https://dog.ceo/api/breeds/image/random.
4+
It should trigger after clicking a button in your webpage. Every time the button is clicked it should append a new dog image to the DOM.
5+
Create an index.html file that will display your random image
6+
Add 2 <button> and 1 <ul> element, either in the HTML or through JavaScript
7+
Write two versions for the button functionality: one with XMLHttpRequest, and the other with axios
8+
When any one of the 2 buttons is clicked it should make an API call to https://dog.ceo/api/breeds/image/random
9+
After receiving the data, append to the <ul> a <li> that contains an <img> element with the dog image
10+
Incorporate error handling -->
