I Made The Fastest JS Framework (please don't use it)
Summary
The main theme is optimizing JavaScript Server-Side Rendering (SSR) performance, with a key focus on a new proprietary framework, "Theo's secret thing," which achieves up to a five times speed increase. The practical takeaway is that while this new method is significantly faster, it's presented as a demo and not recommended for production use, with a sponsor mention for PostHog's product analytics tools.
