Reactivity as Catalyst: Driving Evolution in React, Vue & Angular
summary
Explains why reactivity drove major rewrites and new compilation routes: compares React Fiber and React’s move from reconciliation to compilation, Vue Vapor replacing virtual DOM with compile-time updates, and Angular’s shift toward signals for finer-grained updates. Traces history from three frameworks launching in 2010 (knockout/backbone/angular patterns) to Solid/Svelte-style signals and the coarse-vs-fine-grain reactivity tradeoff, and notes an ongoing proposal to add signals to ECMAScript.
