# 2. 全局API更新
## 全新的全局API
- createApp()
- defineProperty()
- defineAsyncComponent()
- nextTick()
## 将原来的全局API转移到应用对象
- app.component()
- app.config()
- app.directive()
- app.mount()
- app.unmount()
- app.use()
## 模板语法变化
- v-model的本质变化
- propvalue -> modelValue
- eventinput -> update:modelValue
- .sync修改符已移除, 由v-model代替
- <ChildComponent v-model:title="pageTitle" v-model:content="pageContent" />
- v-if优先v-for解析
