Calling a Component in a Loop in Angular

You can also call the component in a loop, passing it various parameters in attributes. Let's try it in practice. Let's say we have the following property with users:

app/user/user.component.tsinterface User {
  name: string,
  age: number
}

class UserComponent {
  public users: User[] = [
    {
      name: 'user1',
      age: 25,
    },
    {
      name: 'user2',
      age: 26,
    },
    {
      name: 'user3',
      age: 27,
    },
  ]; 
}

Let's iterate over the users in a loop, calling the child component with the user in each iteration and passing it the name and age as parameters:

app/app.component.html<div *ngFor="let user in users">
  <user-data [name]="user.name" [age]="user.age"></user-data>
</div>

typescriptinterface Product {
  name: string,
  cost: number
}

class ProductComponent {
  public products: Product[] = [
    {
      name: 'prod1',
      cost: 100,
    },
    {
      name: 'prod2',
      cost: 200,
    },
    {
      name: 'prod3',
      cost: 300,
    },
  ]; 
}
