Write and run code as a code cell. Supports several languages (HTML/CSS/JS, TypeScript, Python).

import Code from '../ww-code-webassembly';

//Import WebAssembly from code mirror for syntax highlighting
import { wast } from '@codemirror/lang-wast';
import { WABT } from "./libwabt";
// bind function to code cell
// capture console calls
// Redirect results to code cell output

const wabt = await WABT()
