You can import C (and many others) libraries without re-implementing it in JS for browsers. In my company's case, we compile C-written libopus almost directly to encode audio streams into Opus on browsers, not on servers. In this way we benefit much less data traffic and server CPU loads.

>You can import C (and many others) libraries This means compiling the lib to wasm, right? At first I was thinking of running JS clientside that imports some C lib somehow, which confused me.

  Yes. The C lib will be compiled into wasm. You can use the wasm-compiled code in a browser through JS wrappers. So you can say importing C lib on JS client side anyway. Note that wasm's main objective is to run non-JS code on browsers, not for a faster JS.

    So you could do the same with Cython then, too? Interesting.

      I've never experienced with Cython. But if Cython is to compile anPython file into a C file then probably.
