For bonus points, compiling to a stand-alone JavaScript wrapped in HTML would be awesome if it could be hosted on a Github page.
Obviously I understand most of the time someone wants to make a GUI they are not thinking about something like TIC-80. I agree a more complete GUI library would be nice.
But if nothing else it may be worth mentioning that TIC-80 is a fun and easy way to install and try Janet. Even the Android version comes with Janet and a built-in code editor. Just run "new janet" in the TIC-80 console and then press F1 (on Android TIC-80 by default uses its own virtual keyboard that has all the keys it needs) to open the code editor.
Similarly, they were supposed to offer "compile to HTML5", but it never really worked for me.
An opinion that flatly and individually labels every extant thing the same has no signal to it. I'm not sure what to make of your original post other than you're expressing displeasure at the universe for not handing you what you wanted and that you believe that expression should be injected into arbitrary discussion.
Should have phrased it as something along the lines of:
>This would be very interesting to me if it had support for a GUI library, and if it were then possible to compile to a stand-alone application which could be easily distributed.
