Vue Reactivity — ref, reactive and computed

Build a real mental model of Vue's reactivity system: what reactivity means, wrapping a single value with ref(), reading it through .value in script versus auto-unwrapping in the template, tracking objects with reactive(), deriving values with computed(), and how the template re-renders the moment state changes.

Learn Vue step by step. These tutorials cover the fundamentals with clear explanations and runnable examples, building from the basics toward confident, working code.

Start with a topic below, and run everything in the Vue online compiler as you go.

Frequently asked questions

Do I need to know JavaScript before Vue?
