1. Ditching React and Angular for this is like ditching Photoshop for MS Paint.
2. Someone using Zam isn't "going vanilla JS", they are going Zam JS.
3. Going into a performance arms race with jQuery is not a one man job. It would be nice to know how you achieve such performance gains. What tradeoffs are involved? Like, is it faster because it uses native dom selection functions? If so, then this is just an extra layer of indirection with no added value over something like a polyfill. If that's not the case, what kind of groundbreaking work did you do here to achieve the impressive looking benchmarks on the Github page?
