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.
