This article and the Find Me In Chicago application was originally written in 2016. I am pleased to say that as of this update, the application still seems to be working just fine. If I were to do a rewrite today, I would definitely not use jQuery. Sorry jQuery, I still appreciate all you have done for the web and I am impressed at your longevity. However, there is no denying today’s more robust frameworks like React or Angular with Material Design would be the obvious path forward.
