Make createMemo depend on unmentioned signal

I have a

createMemo

createMemo

that depends on a list of objects

  const items = createMemo(() => props.articles.map((article) => article.id));

  const items = createMemo(() => props.articles.map((article) => article.id));

now, when I reorder that list of objects, the createMemo does not fire again, since I guess the content staid the same.

Now I defined

  const [reorderTag, setReorderTag] = createSignal(0);

  const [reorderTag, setReorderTag] = createSignal(0);

that I increment each time I reorder the list.

Short of

  const items = createMemo(() => {
    console.log(`reorderTag: ${reorderTag}`);
    return props.articles.map((article) => article.id)
  });

  const items = createMemo(() => {
    console.log(`reorderTag: ${reorderTag}`);
    return props.articles.map((article) => article.id)
  });

how do I make sure it refires? Making logic depend on

console.log

console.log

feels dirty.
