I have to say this is a pretty shitty RSS reader but is pretty impressive to be written by a robot.<p>Some thoughts on first reading.<p>- Only supports the RSS format.<p>- Crashes if some properties are not available.<p>- Dark mode toggle is never actually read. Instead the internal value is just changed on every click. Mostly poor coding style.<p>- It used textContent so no HTML injection! Although it just avoided showing the entry content at all. Which would require safely rendering untrusted HTML.
