WASM cannot magically load from disk, there is browser protection, right?

  It can't access the file system, but it could implement an API that emulates a file system inside the browser sandbox. Presumably that's what they're doing here.

    But you can do that same API emulation in regular browser JavaScript, too. What's the WASM intermediate buying here?

      I think it is more complicated to emulate those api in normal browser environment compared to emulating some OS api for running node.js.

        Why? It's literally JavaScript on both sides - what's complicated here?
        • maple3142 5y ago
          Because many node.js api are written in C/C++, it might be easier to implements OS features instead of rewriting in JS. This is just my assumption.
