Could you build this?
No Designing and building a reactive engine from scratch requires specialized computer science knowledge of fine-grained dependency graphs, reactive primitives (signals, effects), and memory lifecycle optimizations.
What it would actually take: Building a custom reactive engine requires deep knowledge of topological sorting, dynamic dependency tracking (sub/pub directed acyclic graphs), memory leak prevention via WeakRefs, and batched queue scheduling. The core challenge is avoiding glitching (inconsistent intermediate states) and achieving micro-benchmarked performance comparable to modern signals implementations. This demands specialized domain knowledge in JavaScript runtime optimization and reactive programming theory.
