Angular 6 Pipe that gets only the first word of a string.

first-word.pipe.ts

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

@Pipe({
  name: 'firstWord'
})
export class FirstWordPipe implements PipeTransform {

  transform(value: string): string {
    if (!value) { return ''; }
    return value.split(' ')[0];
  }

}

thanks
