Cannot start TeaVM-compiled JavaScript code from Web Worker using eval()

[WorldEditAxe]

Hello there, I'm attempting to create a self-contained JavaScript file that spawns workers of itself. My approach fetches the JavaScript file, eval()s it, and then calls main() (defined by TeaVM output JavaScript file). However, main remains undefined. Despite numerous attempts/approaches I've tried, I was unable to launch the worker script.
Here's my JavaScript code:

fetch('%s').then(response=>response.text().then(script=>{globalThis.eval(script);main();}))

I've tried different dynamic code execution methods, but none of them worked. Is there something I'm doing wrong?

Instead of eval, did you try using importScript? As for your code, eval creates a separate scope, and main is defined there, not in the scope that actually calls main. With eval-based approach it would look something like that:

fetch('%s').then(response=>response.text().then(script=>{globalThis.eval(script + ";main();");}))

Thank you for your response! Your suggestion worked, but I was able to alternatively get it working by converting the JavaScript file into a Function, appending \nmain(); to the end of it, and binding it to globalThis. I'll probably take and use your suggestion for the foreseeable future, seeing that it doesn't mangle the JS source and is more readable.
