A drawback is that the content isn't directly crawlable by search engines.

I made an app earlier that uses Javascript to make static sites dynamic using Javascript, but got lots of comments saying that it's anti-seo:

SEO is fine when pre-loading the content and hiding it.

Hmm, how would you use Javascript to preload content that is crawlable by search engines?
