Learn how replacing classic Ember computed properties with @tracked fields and autotracking gives fine‑grained reactivity, reduces boilerplate, and avoids stale UI.
Use $state, $derived, and $effect for component-local reactive state in Svelte 5, and keep stores for cross-component state.
SolidJS replaces virtual‑DOM diffing with fine‑grained reactivity. Learn how signals and effects let you write efficient UI code, illustrated with a counter example and trade‑off discussion.
Alpine.js $watch is a side-effect hook, not a general observer. Learn when to use computed getters, how to fix silent array watchers, and what breaks in legacy browsers.
Learn how to create shared Svelte stores, subscribe with the $ prefix, update immutably, and avoid SSR and memory pitfalls.
When building a SolidJS app you’ll often face a choice: use createSignal for simple atomic state or createStore for nested, relational data. This guide compares the two, explains trade‑offs, and shows a concrete example that validates reactivity isolation.
SolidJS’s signals, selectors, and memo primitives let you limit re‑renders to only affected components. Learn how to use them, check the reactive graph, and avoid common pitfalls with a hands‑on example.
