Not really, you can call any async function in JS in sync code. It is automatically scheduled, and it will return a result immediately. This result is a Promise, that you can pass sync callbacks to, and keep the whole code away from async/await. You can also decide that async/await is nice, and just use that instead. I'm a Python dev, but that part is better in JS.
