Introduction into the Composition API
summary
Claims that the Composition API makes large components readable by organizing code by feature and enabling reusable composition functions backed up with concrete code: reactive refs and reactive objects, computed and watch usage, and the setup function where setup executes before lifecycle. Example builds a capacity/attending list with an increment method and computed spacesLeft that works in the browser. Notes Vue 3 is optional, usable in Vue 2 via plugin, and the conference lists 2494 attendees.
