Vue 3 and Composition API
summary
Demonstrates Vue 3’s Composition API by showing concrete code for a live counter using the setup() function with ref, reactive, and computed to manage reactive state in templates, plus watch and lifecycle hooks inside setup. Explains composable functions that extract reusable feature logic from options objects with no runtime overhead, includes import examples, a brief migration note, and a working browser demo that updates on click.
