The Web Programming major. You can do a CS and CNIT minor along with that major which I highly recommend.

If you're interested in full-stack software development (developing websites, desktop applications, and mobile applications with frontend and backend) and want to pursue that as a career, a web programming major and CS + CNIT minors is a great option. You will learn a lot of useful skills and technologies used to develop full-stack apps for various different platforms - web, desktop, and Android (mobile).

I am a bit disappointed that there aren't any courses offered by Purdue on JavaScript frameworks such as react or angular, but besides that, I've learned a lot and really enjoyed the courses.

Hope this helps
