Vue全局注册与局部注册异同点

Vue.component('myheader',header),
Vue.component('mycontent',content),
Vue.component('mybottom',bottom),

export default {
  name: 'app',
  components:{
    'myheader':Header,
    'mycontent':Content,
    'mybottom':Bottom
 
  }
}

import Header from './components/header'
import Content from './components/content'
import Bottom from './components/bottom'
