FWIW, I did try. Many languages now have websites where one can experiment with an interpreter or compiler. I've used them for playing with JavaScript, APL, Python, etc. Strangely, there does not seem to be one for FORTH. SwiftForth from forth.com does not work with 64-bit Intel Mac OS-es like Catalina which is what I have [1]. I tried gForth as well but during the installation, it invoked HomeBrew which gave a series of hostile messages that my system is obsolete and to not bother asking for any help or support. See [2] and the output provided by the poster - it is what I saw in my case.
