I would think that a hypothetical `client.get` method would reject when an
error occurred, so that you wouldn't need to attach an "error" handler.

That said, you can also freely mix promises with await and async:

    async function fetchish() {

        let text = await new Promise((resolve, reject) => {

            let client = new Client;
            client.on("error", reject);
            resolve(client.get());
        });

        return JSON.parse(text);
    }
