The Wasm code is not behaving as expected.

I recently wrote a demo program for diaphragmatic breathing, which runs normally on Windows. However, after packaging it into Wasm, it doesn't execute as expected when accessed through a browser. I'm unsure what the problem is.

What do you mean as "not execute as expected"? Do you have a panic or anything in the web console?
How exactly do you build and embed it?

Thank you for your reply! It runs fine on Windows 11.

but when packaged as a Wasm installation, it freezes. The Wasm demo can be found here.
There's no panic message in the web console. I don't know how to troubleshoot it.

It freezes for me in Chrome as well, but in Safari I get this:

[Error] RuntimeError: Unreachable code should not be executed (evaluating 'wasm.wasm_bindgen__convert__closures_____invoke__hcff31c1dd8f58dfc(arg0, arg1)')

Bummer that source maps aren't working with Safari :(
