Angular中的ViewContainerRef的几个概念和总结

今天读到博客：https://www.tuicool.com/articles/6Vzmuuv 现总结一下提到的全部语法。

其中涉及几个标签：

<template>  : HTML的标准标签，不建议使用

<ng-template>:   <ng-template> tag will be rendered as a comment element,   but is's content will be inserted

<ng-container>:The Angular <ng-container> is a grouping element that doesn't interfere with styles or layout because Angular doesn't put it in the DOM.
