I need another solution to the code I've built.

Dave McFarland, I made a JavaScript program that generates different colors in each rectangle without refreshing the page. Hint: I use Ajax. The code in app.js isn't good and I need your help to refactor it so that my code can be clean. One more thing, I named the variables poorly, and I just wanted you to know that. Here is the link to my program: https://w.trhou.se/iwdgwtjafs.

Happy Coding, Diego Salas

Here's a few suggestions.

While you're waiting for Dave, I was wondering what role AJAX performs here. It doesn't look like you get any new data so it seems like you could refactor the program to work without it.

Also, it looks like every call to randomRGB creates a new interval that calls itself when it fires, so in just a few seconds there would be an exponential increase in active intervals. You might want to reconsider your intended functionality, and I'd bet you can do what you want with just one interval (or a small fixed number) and no recursion.

Also, you have some rendering HTML in your head area. That h1 tag should be moved into the body.
