Online REPLs are great, but students especially in CS should know how to set up their environment. I remember being a Junior Compsci student watching other students struggle to install the Java JDK on their Windows laptops (install JDK not JRE; configure PATH; install Eclipse; point it at the JDK). The professor had to come around and help them. I was the only student with a Mac and I had transferred from a community college where we had already learned Java in the first semester, including how to install and set up a local environment. All of this to say I feel like colleges should better prepare students to set up their local environments, although I see how useful the online REPL options are for getting started.
