    tags: item.tags ?? []
  }));
}

FAQ

Does this beautifier javascript route run entirely in browser?

Yes. The formatter runs in browser so pasted code or styles stay local while you review and copy the result.

Does this route return copy-ready beautified javascript?

Yes. After formatting, the result stays in the shared output workspace so you can inspect and copy it immediately.
