Speeding up the JavaScript ecosystem – Polyfills gone rogue
Many popular npm packages depend on 6-8x more packages than they need to. Most of these are unnecessary polyfills and it's one of the key reasons node_modules folders are so large. The eslint ecosystem seems to be most affected by this.

Towards Principled Reactive UI
Update 7 May 2022: A followup to this post containing significant conceptual advance is Xilem: an architecture for UI in Rust. I consider the Crochet experiment to be mostly negative, as there were a number of ergonomic and functional “paper cuts,” though several of the research goals were met, at least to some extent.
