what is the "it" for?

[ralyodio]

I seem to have to use it although your examples don't always use it.

@chovy it represents the object in which template data is stored - you can configure it to use a different name or have it dumped in global scope with with in a sense.

Please use GH discussions for questions, I will be converting this issue to a discussion.

It appears that I can modify it object as well.

          if (!it.pinyin) {
            const r = await fetch(`https://zhres.herokuapp.com/api/vocab/match`, {
              method: 'POST',
              body: JSON.stringify({ entry: it.chinese }),
              headers: { 'Content-Type': 'application/json' }
            })
            if (r.ok) {
              const { result } = await r.json()
              if (result[0]) {
                it.simplified = result[0].simplified
                it.traditional = result.map(r => r.traditional).filter(r => r).filter((a, i, r) => r.indexOf(a) === i)
                it.pinyin = result.map(r => r.pinyin).filter((a, i, r) => r.indexOf(a) === i)
                it.english = result.flatMap(r => r.english.split('/')).filter((a, i, r) => r.indexOf(a) === i)
              }
            }
          }

          if (!it.pinyin) {
            it.pinyin = [toPinyin(it.chinese)]
          }
        %>

I did not notice this message before, but this is interesting and probably a security vulnerability. I will probably open a PR/issue on this soon.
