I recently had an angular interview and encountered this question. The interviewer inquired about the meaning of the following code snippet in Angular:
code;
<app-main [type]="text"></app-main>
This is an example of the property binding syntax using square brackets []
notation.
The value of the text
variable from the component is being passed to the child component app-main
.
In the app-main
, it expects a value to be passed down like this:
@Input() type: string;
You can learn more about this at this link.
Input in the app component is received from the current view using a decorator called @Input
. It is passed as [xyz]
.
To declare this input in the app component, you need to create a variable like this:
@Input('xyz',{static:true / false }) myVariableInAppComp ;
You can now freely use myVariableInAppComp
in your app component.
The parameter static:true/false
refers to lifecycle hooks that you should explore further.
