Angular 2 ngSwitchCase, OR operator not working

I think this syntax is better:

    <ng-container [ngSwitch]="options">
        <ng-container *ngSwitchCase="'a'">Code A</ng-container>
        <ng-container *ngSwitchCase="'b'">Code B</ng-container>
        <ng-container *ngSwitchCase="'c'">Code C</ng-container>
        <ng-container *ngSwitchCase="['d', 'e', 'f'].includes(options) ? options : !options">Common Code</ng-container>
        <ng-container *ngSwitchDefault>Code Default</ng-container>
    </ng-container>

If you evaluate 'd' || 'e' || 'f' the result is 'd' and when options is not 'd', then it doesn't match. You can't use ngSwitchCase that way.

This would work:

    <ng-container [ngSwitch]="true">
        <ng-container *ngSwitchCase="options === 'a'">Code A</ng-container>
        <ng-container *ngSwitchCase="options === 'b'">Code B</ng-container>
        <ng-container *ngSwitchCase="options === 'c'">Code C</ng-container>
        <ng-container *ngSwitchCase="options === 'd' || options === 'e' || options === 'f'">Common Code</ng-container>
        <ng-container *ngSwitchDefault>Code Default</ng-container>
    </ng-container>

Thanks Bahador R, helped me create a pipe.

import { Pipe, PipeTransform } from '@angular/core';

@Pipe({
    name: 'switchMultiCase'
})
export class SwitchMultiCasePipe implements PipeTransform {

    transform(cases: any[], switchOption: any): any {
        return cases.includes(switchOption) ? switchOption : !switchOption;
    }

}

use as

<ng-container [ngSwitch]="switchOption">
...
<div *ngSwitchCase="['somecase', 'anothercase'] | switchMultiCase:switchOption">
