ngPlural directive

This is the documentation for Angular 8.
You can switch to the latest version Angular 9.

Adds / removes DOM sub-trees based on a numeric value. Tailored for pluralization.

To use this directive you must provide a container element that sets the [ngPlural] attribute to a switch expression. Inner elements with a [ngPluralCase] will display based on their expression:

if [ngPluralCase] is set to a value starting with =, it will only display if the value matches the switch expression exactly,
otherwise, the view will be treated as a "category match", and will only display if exact value matches aren't found and the value maps to its category for the defined locale.

See CLDR — Plural Rules.
