ng-pluralize in modern Angular

<ng-pluralize count="vm.messages.length"
  when="{'0': 'No messages',
         'one': '1 message',
         'other': '{} messages'}">
</ng-pluralize>

<!-- ICU expression, extracted for translation by the i18n attribute -->
<span i18n>
  {count(), plural, =0 {No messages} =1 {1 message} other {{{ count() }} messages}}
</span>

<!-- or I18nPluralPipe, with the mapping in the component -->
<span>{{ count() | i18nPlural: messageMap }}</span>

messageMap = { '=0': 'No messages', '=1': '1 message', other: '# messages' };
