what is [(selection)] in Angular 8?

Question

• Is it the same as [(ngModel)] ? Some kind of two-way binding ?

• I do have the following tag on our project :

           <p-table #tt [value]="universitiesList"[(selection)]="selectedUniversity" [globalFilterFields]="['Name']">
  

• universitiesList and selectedUniversity are 2 variables which exist on the typescript of this component. I understand that. But are 'value' and 'selection' reserved words ? Why is value writen with [] and selection written within [()] ?

Ty a lot

Answer 1

• [(selection)] is a property of a primeNG table

• It is a form of two-way-binding

• When a row / checkbox of the table is selected, the value is saved to that array (the value is saved to the array"selectedUniversity") :

              [(selection)]="selectedUniversity"

<p-table [columns]="cols" [value]="cars" selectionMode="single" [(selection)]="selectedCar1" dataKey="vin">
