Can anyone explain me this?

Question

A few time ago I saw this code and wondered how it works, In this code c++ is compiled in JS?

The code:
https://code.sololearn.com/W9AOylZ8qFn7/?ref=app

The above code was not created by me its just a copy of original code , whose url is mentioned in the code.

Answer 1

No, the c++ code is not compiled in JS... and this will not work in a "normal" web page, but only in sololearn code playground context: I guess that original author hack code playground features for other languages, which are handled through web request ^^

But the better way to get accurate answer, would be to directly ask the code author, through the comment section of the related code ;P
