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:

interface 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:

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

The following array of products is given:

interface Product {
	name: string,
	cost: number
}

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

Loop through this array, creating a new component with a product each time.
