# 2. Kernkonzept

<img height="400" src="https://012.vuejs.org/images/mvvm.png" />

???

- VueJS ist ein einfacher und flexibler view layer
- Fokus auf Komposition und Funktionalität
- Kann für kleine Projekte verwendet werden gibt aber die Möglichkeit zu skalieren
- Verbindet die View mit einem Model mittels 2way Databinding
- API ist stark beeinflusst durch AngularJS und KnockoutJS

---

# 2. Kernkonzept

<a href="https://jsbin.com/vuxesaz/edit?html,js,output" target="_blank"><img height="300" src="https://vuejs.org/images/components.png" /></a>

???

- Können mehrere Vue Instanzen auf einer Seite existieren
- Eine Instanz teilt sich in einen Komponenten Baum auf, der wiederum einzelen Vue Instanzen enthält
- ViewModel // var vm = new Vue({ /* options */ })
- View // vm.$el
- Model // vm.$data
