Helper functions can also be a thing.

const getJSON = async (url, callback) => {
  const response = await fetch(url);
  const data = await response.json();
  callback(data)
}

getJSON("/my/url", console.log);

I understand where you're coming from, but for modern Internet speeds 30kb is nothing. Sure, it's worth taking into account if you're launching a site for a territory which suffers from slow Internet speeds, but for most affluent countries I'd argue 30kb is not worth losing sleep over.

In the UK the average Internet speed in 2015 was 13 MBps. https://www.mindgems.com/info/file-download-time-calculator/?FileSize=30&Units=kilobytes It really takes no time at all to download such a tiny file.
