Component to View using interpolation

This is one of the ways of bindings provided by the Angular framework. For this one, we need to have a class level property in our Component class which we use in our HTML using double curly braces.

For example, the below code snippet shows a piece of code in the component class. There are 3 properties: department, imgURL and

showspinner, out of which imgURL and showspinner are already initialized, whereas department is just declared.

   department: Any;  
   imgURL: string =  "assets/photos/Department.jpg" ;  
   showSpinner: boolean  = false ;   

In our HTML file, these properties are used inside double curly braces to render these values directly on the browser. In our case, the imgURL represents the source of the image so that has to be used in the below manner, as shown in the below code snippet.

  <image src = {{imgURL}} >
