How to compile ffish.js into a version that can be converted by browserify?

[yjf2002ghty]

I'm trying to test my recent pull requests by putting the results into Fairyground and have some further runs.
However, when I compiled ffish.js, browserify is unable to make the conversion to CommonJS which makes it runnable in a browser. None of the following commands worked:
make -f Makefile_js build
make -f Makefile_js build es6=yes

Browserify keeps showing the following error:

SyntaxError: Unexpected token (716:26) while parsing E:\Chess\new\fairyground-main\node_modules\ffish-es6\ffish.js while parsing file: E:\Chess\new\fairyground-main\node_modules\ffish-es6\ffish.js

I've also checked the difference between the compiled file and the file comes from NPM package. It seems that the compiled version from Makefile adds a lot of __syscall objects while the distributed one does not.

You are compiling on windows, right? Generally the compiled WASM should be assumed to be platform independent, but I have never compiled it on windows, so I don't know whether that might explain the difference. You could maybe try to run it on Linux or WSL if you haven't already to check. If I find the time I might also try to reproduce myself as well, but can't promise.

After I compiled it in Linux, it solved the problem. So the solution is to compile it in Linux.
