Hi,
I previously tried to post a longer question as to whether developers can use web assembly files with DroidScript but am not sure the message got sent.
I tried using an already released node.js package:
https://www.npmjs.com/package/webr
but couldn't get it to work using DroidScript node app (npm package installed fine but crashes every time it tries to initialize .wasm).

I also tried to make a straightforward DroidScript html app using the following developer's example:
```
<html>
<head>
<title>WebR Test Console</title>
</head>
<body>
<div>
<pre><code id="out">Loading webR, please wait...</code></pre>
<input spellcheck="false" autocomplete="off" id="input" type="text">
<button onclick="globalThis.sendInput()" id="run">Run</button>
</div>
<script type="module">
/* Create a webR console using the Console helper class */
import { Console } from 'https://webr.r-wasm.org/latest/webr.mjs';
const webRConsole = new Console({
stdout: line => document.getElementById('out').append(line + '\n'),
stderr: line => document.getElementById('out').append(line + '\n'),
prompt: p => document.getElementById('out').append(p),
});
webRConsole.run();
/* Write to the webR console using the ``stdin()`` method */
let input = document.getElementById('input');
globalThis.sendInput = () => {
webRConsole.stdin(input.value);
document.getElementById('out').append(input.value + '\n');
input.value = "";
}
/* Send input on Enter key */
input.addEventListener(
"keydown",
(evt) => {if(evt.keyCode === 13) globalThis.sendInput()}
);
</script>
</body>
</html>
```
which also doesn't work in a DroidScript html app but does work using a generic javascript IDE.
Appreciate any advice anyone can offer.
Thanks and best wishes to everyone for a good new year!

I'm pretty sure I have had WASM working in a webview at some point, but I can't remember what it was.... possibly it was Python with this project -
