Why fast reactivity beyond the DOM: Q&A and introduction to Raph

This article explores the necessity of high-performance reactivity in modern web applications that goes beyond standard DOM manipulation. The author details the architecture of the Raph and Nova libraries, explaining how a single reactive core can efficiently manage both DOM elements and Canvas graphics. The material covers practical use cases, including rendering complex graphs, timelines, and interactive maps. Special attention is given to performance benchmarks that demonstrate the advantages of this approach when handling large datasets. The author addresses common developer questions regarding why reactivity optimization is critical even when constrained by browser rendering, and shows how unifying tools allows for the creation of more responsive and scalable interfaces for a wide range of tasks.
