Introduction to Vue 3's Composition API
summary
Composition API is presented as an alternative not a replacement to the Options API and signals itself with the setup function; the talk shows concrete code using helper imports from Vue — ref, reactive, toRefs, computed — to make a counter reactive, unwrap values with .value, and keep templates tidy. A small space‑themed game is built as a learning exercise and it works. Advice is practical: learn composables and avoid rewriting a working app wholesale.
