JavaScript AJAX Basics Programming AJAX Create a callback

Some videos out of date

In this AJAX basics chapter, some of the questions use "var" and don't allow use of "let" or "const". Also, this ch. does not allow arrow functions. This is confusing and harmful to students...

The answer is for Treehouse to update these extremely old videos

I would say embrace it. You will stumble across legacy code in the wild, among other things. Treehouse staff try to keep up to date and generally do a great job at it. Being able to work through things like this is annoying but beneficial.

I understand that, but treehouse is a teaching resource, so Imo it's a different story. For example, if too much of their content goes out of date, customers may choose competitors such as code academy instead.

Appreciate the feedback, Daniel Ahn, it will definitely be passed along to the Content Team!
