Could you build this?
No Developing an ultra-minimal (1.5–2.7KB) reactive UI library with zero dependencies requires deep systems-level mastery of JavaScript runtime internals, DOM diffing/signals, and micro-optimizations.
What it would actually take: The project consists of an ultra-lightweight reactive core and DOM renderer adhering strictly to web standards without a build step. The challenging aspects are architecting fine-grained signal tracking, dependency subscription graphs, and efficient DOM reconciliations within an extreme sub-3KB budget. This requires specialized knowledge of JavaScript engine performance, reactive primitives, and low-level browser APIs.
