Yep. I’m a JS dev who gets offended when people complain about JS-sites being slower because there’s zero technical reason why interactions should be slower. I honestly suspect a large part of it is that people don’t expect clicking a button to take 300ms and so they feel like the website must be poorly programmed. Whereas if they click a link and it takes 300ms to load a new version of the page they have no ill-will towards the developer because they’re used to 300ms page loads. Both interactions take 300ms but one uses the browser’s native loading UI and the other uses the webpage’s custom loading UI, making the webpage feel slow. This isn’t to exonerate SPAs, but I don’t think it helps to talk about it as a “JavaScript” problem because it’s really a user experience problem.
