here's how you can use it to "just-in-time" compile and run any C (or C++) code you'd like:
![import { runClang } from 'npm:@yowasp/clang';
await runClang(['clang', '--version']);
const { 'a.out': wasm } = await runClang(['clang', '-nostdlib', '-Wl,--no-entry', 'test.c'], {
'test.c': 'int add(int a, int b) __attribute__((export_name("add"))) { return a + b; }'});
const module = await WebAssembly.compile(wasm);
const instance = await WebAssembly.instantiate(module);
console.log('add(1, 2) =', instance.exports.add(1, 2)); // add(1, 2) = 3](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:zluwetzklecudcv33x2bmkwc/bafkreicbbrj7q2p5q57alsjhnbvh6cm2zme7ccaiamrzwizg4iuevzpxiq@jpeg)
