I'm not sure if the parent did, but I followed what you were looking for and the answer is still "try clojure", perhaps more specifically it is "Try the Clojure libraries figwheel and devcards to do web stuff" but the push for immediate feedback and "interactive programming" is central for everyone. It's a community that took Bret Victor's Inventing on Principle talk to heart, already agreeing due to the REPL centric workflows that most people used.
Bruce Hauman has some good talks about his tools, which are GUI application-centric and a joy to use [1][2][3]
If you aren't doing web or native mobile GUI stuff then the default tools have immediate unit test/linting/spec compliance feedback triggered every time you save a file.
Unless you mean you want a very simplified language, in which case you should look elsewhere. Clojure has definitely chosen the high power side of that trade-off, but this also allows some truly first class tools to be developed.
