Introduction to Vue

Vue is a frontend framework designed to be approachable — you can drop it into a single page for a small feature, or build an entire app with it, unlike frameworks that require a full project setup upfront.

Vue templates look like enhanced HTML: `{{ message }}` displays a reactive value, and directives like `v-if` and `v-for` add logic directly in markup.

Vue's reactivity means changing a piece of data automatically updates every part of the page that displays it — you describe the relationship once, and Vue keeps the DOM in sync.
