Well… a couple of things that could be done better in that example:

—⁂—

  const [data, setData] = useState<Array<Array<object>> | undefined>();

That type stinks. Kill the undefined bit by giving it an initial value, then you can skip the `?? []` later too; and replace Array<object> with the actual row type, probably naming it, maybe like this:

  type Record = [string, number, number, number, number];
  const [data, setData] = useState<Record[]>([]);

—⁂—

  const params = Object.entries({ aroma, flavor, acidity, sweetness })
    .map(([k, v]) => `${k}=${v}`)
    .join("&");

No need to construct the query string manually:

  const params = new URLSearchParams({ aroma, flavor, acidity, sweetness });

I confess I’m puzzled about this one too, as trailbase.js suggests you know about URLSearchParams, which is what you should use for all typical query string manipulation, parsing and generation.

Done. Thanks
