SolidJS Fundamentals
Reactive primitives, fine-grained DOM updates, and the JSX-without-virtual-DOM model. Nine lessons covering createSignal, createMemo, createEffect, stores, and control-flow components (Show, For, Switch). If you know React, the syntax looks familiar; the execution model is what to learn.
