Component class methods in Angular template

In the layout, you can also call public methods of the class. Let's see in practice. Let's say we have the following method:

export class AppComponent {
	public show() {
		return 'abcde';
	}
}

Let's call it in the layout:

<div>
	{{ show() }}
</div>

Let the component class have the following methods:

export class AppComponent {
	public showName() {
		return 'john';
	}
	
	public showSurn() {
		return 'smit';
	}
}

Display the first and last name in the component template file.
