Press me!

</body>
</html>
`;
const webview = new Webview();
webview.navigate(`data:text/html,${encodeURIComponent(html)}`);
let counter = 0;
// Create and bind `press` to the webview javascript instance.
// This functions in addition to logging its parameters also returns
// a value from deno land to webview land.
webview.bind("press", (a, b, c) => {
console.log(a, b, c);
return { times: counter++ };
