What you will learn
- script setup makes components concise and type-friendly.
- Composables share stateful logic the way hooks do in React.
- Pinia stores are typed, modular and devtools-friendly.
Why the Composition API won
The Options API organised code by type: data here, methods there, watchers somewhere else. In large components a single feature was scattered across all of them.
The Composition API organises code by feature. With script setup, everything declared at the top level is available in the template, and logic can be extracted into composables.
