Yes, I said most and not all, there are still some older libraries that haven't been updated. These are fairly rare, and you can still util.promisify, but sure

Yes, I said most and not all, there are still some older libraries that haven't been updated. These are fairly rare, and you can still util.promisify, but sure it's definitely not ideal. Please note that not all callbacks can (or should!) be converted to promises, e.g. events like `on('click', ...)` don't have a clear way to be promisified since a promise can only be resolved once and stays resolved.
