What are Template Variables?
As we’ve seen in the description itself, by using template variables we can use data from one part of the template to another part of the same template. Now let’s see the places in the template where template variables can be used.
- DOM Elements within a Template: using the template variables we can create a reference to a specific DOM element within the template. This allows us to access that particular DOM element or its value programmatically.
- Directives or Components: By using the template variables we can also refer to the directives or components. For example, using a template variable we can refer to a form component to collect its data.
- TemplateRefs from an ng-template: Suppose we’re using Angular’s <ng-template> then by using template variables we can refer to the template itself. It is handy when working with structure directives.
