ELI5: Explain Like I'm 5

user experience

User experience (often shortened to UX) is about how you FEEL when you use something. It's about the experience you have when you use a website, an app, a car, or even when you go shopping at the store. UX is about making sure that the thing you're using is easy to use and enjoyable. It also focuses on making sure that whatever you're using helps you accomplish what you need it to do.
