“If the sanitization logic in DOMPurify is buggy, your application might still have a DOM XSS vulnerability. Trusted Types force you to process a value somehow, but don’t yet define what the exact processing rules are, and whether they are safe.” — this caution from web.dev makes me want to play around with TrustedTypes more and get a better understanding. - Source: dev.to / 20 days ago

Before we start creating pages in our application, it's important to understand how Next.js renders content.

I am running tests using webpagetest.org, and I am having trouble fully understanding the speed index results as well as the film strip view. The page renders quite fast everywhere I test it.
