@Component({
selector: 'lowerupper-pipe',
template: `<div>
<label>Name: </label><input #name (keyup)="change(name.value)" type="text" />
<p>In lowercase:</p>
<pre>'{{ value | lowercase }}'</pre>
<p>In uppercase:</p>
<pre>'{{ value | uppercase }}'</pre>
</div>`,
standalone: false,
})
export class LowerUpperPipeComponent {
value: string = '';
change(value: string) {
this.value = value;
}
