- * In the following example, `RepeatPipe` repeats a given value a given number of times.
+ * In the following example, `TruncatePipe` returns the shortened value with an added ellipses.
*
- * ```ts
- * import {Pipe, PipeTransform} from '@angular/core';
+ *
*
- * @Pipe({name: 'repeat'})
- * export class RepeatPipe implements PipeTransform {
- * transform(value: any, times: number) {
- * return value.repeat(times);
- * }
- * }
- * ```
+ * Invoking `{{ 'It was the best of times' | truncate }}` in a template will produce `It was...`.
*
- * Invoking `{{ 'ok' | repeat:3 }}` in a template produces `okokok`.
+ * In the following example, `TruncatePipe` takes parameters that sets the truncated length and the
+ * string to append with.
+ *
+ *
+ *
+ * Invoking `{{ 'It was the best of times' | truncate:4:'....' }}` in a template will produce `It
+ * was the best....`.
