Will this reformat minified, single-line JavaScript?

This tool re-indents existing line breaks rather than reflowing minified code — it works best on code that already has reasonable line breaks but inconsistent indentation.

Does it handle template literals and comments correctly?

Yes — it tracks string and comment boundaries so brackets inside them don't throw off the indentation.

Is this the same as a tool like Prettier?

No — this is a lightweight bracket-based re-indenter, not a full AST-based formatter. For complex reformatting needs, a dedicated build-tool integration is more appropriate.
