Defining createSignal inside a SolidJS component resets state on every render. Declare signals at module level instead.
MobX computed values automatically derive UI state from observables, memoizing results and eliminating manual sync code. This blog shows a concrete todo‑list example, verification steps, and the trade‑offs to watch for.
Decide whether to use Svelte 5 runes ($state, $derived, $effect) or legacy $: statements for new components. Compare trade-offs, see a working runes-only example, and learn how to validate reactivity in mixed codebases.
Avoid redundant recalculations in SolidJS by memoizing expensive derived signals with createMemo.
Switch from Vue’s tangled Options API to the Composition API and gain feature‑based grouping, explicit public APIs, and reusable composables. Learn how to build a counter composable, test it, and understand the trade‑offs.
SolidJS components run once. Learn how createMemo tracks signal dependencies so derived lists update automatically instead of staying stuck on the first render.
Own SolidJS UI state with createSignal, createMemo, and createEffect while avoiding stale DOM and broken reactivity.
A concise architecture note on when to use x-effect, how its dependency tracking works, what boundaries to respect, and how to verify correct behavior.
Learn when to use Signals, Stores, and Context in SolidJS to maintain fine-grained reactivity and avoid common pitfalls like reactivity loss through destructuring.
