Visual Studio Code, Atom and Vim also have great Clojure support. (edit: might be worth to add editors and IDEs to the Clojure landing page to illustrate that there are many solid options by now)

With ClojureScript you can leverage JavaScript runtimes like browsers.

The ClojureScript testsuite also passes using the recently released hermes runtime (https://twitter.com/mfikes/status/1149360258994847745)

edit: Just wanted to add that being familiar with Java or the JVM isn't necessary to get into Clojure. It definitely is not a prerequisite :)
