As sometime who's never used Wolfram Languages before this project has gotten me interested.

For sometime now I've been looking into a good CAS for my app. I've tried a few algebra problems with Sympy, Sage, Xcas, Maxima and Woxi. Of these only Sage, Maxima and Woxi were capable of giving the expected answers.

After trying it out I became fascinated by Wolfram language and other term rewriting languages they are pretty interesting even though most have little to do with CAS like WL.

Anyway I've been looking at this project and plan to seriously use it in the future. So, I've noticed a few things when attempting to run wljs (I had to wrap it with a shell script to get wljs to see it as wolframscript executable). First the version number system variable gives a string instead of the expected real number type (As a temporary hack I modified Woxi to give what wljs expects). There also is a variable that tells to the absolute path of the of the current file and it is wrong when it's used in an imported script. After working around that with hard coded paths things became more difficult.

Edit: just checked my pc and the variables are called $VersionNumber and $InputFileName which is incorrect if the file is evaluated via Get["filepath"].

Anyways, I'm interested in helping out don't know if I can.
