title: NgIf and NgSwitch in Typescript Instead of Html Possible?
body: <p>Is it good practice to utilize Html *NgIf and *NgSwitch in Angular? If someone does this, both business rendering logic is in the front-end html files, and the backend .ts files.</p>
  
  <p>Additionally, business logic is split in two area layers.</p>
  
  <p>Does Angular have any typescript ts file way of using NgIf, instead of utilizing html?</p>
