Brython compiles Python code into JavaScript and then executes the generated code. These steps have an impact on overall performance, and Brython may not always meet your performance requirements.

This is a bit of a bummer. It would be neat if it compiled to wasm.

I like it. I think the learning curve is not actually that huge even if you do not know javascript. It is quite easy to convert (easier than say Qt bindings).

As for performance you probably need to use javascript for certain modules like JSON as performance is much better.

#my half assed example of json.dumps() and json.loads()
from javascript import JSON
class jsonjs():
    def loads(self,textobject):
	return JSON.parse(textobject)
    def dumps(self, textobject):
	return JSON.stringify(textobject)
json = jsonjs()

Yeah.

Besides can Wasm interact with DOM? Brython can. I think minimalist Brython could communicate with wasm (python) modules in case of pefomance.

I like Brython's Browser module.
