In this article, we are going to see what is getLocaleEraNames in Angular 10 and how to use it.

The getLocaleEraNames is used to get the Gregorian-calendar eras for the given locale.

Syntax:

getLocaleEraNames(locale: string, width: TranslationWidth)

NgModule: Module used by getLocaleEraNames is:

  • CommonModule

Approach: 

  • Create the angular app to be used
  • In app.module.ts import LOCALE_ID because we need locale to be imported for using get getLocaleEraNames.
import { LOCALE_ID, NgModule } from '@angular/core';
  • In app.component.ts import getLocaleEraNames and LOCALE_ID
  • inject LOCALE_ID as a public variable.
  • In app.component.html show the local variable using string interpolation
  • serve the angular app using ng serve to see the output.

Parameters:

  • locale: A string containing locale code with rules.
  • width: The character width.

Return value:

  • array: array containing era names.
