  • Last Updated : 28 Apr, 2021

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

The getLocaleCurrencySymbol is used to get the currency symbol for the given locale.

Syntax:

getLocaleCurrencySymbol(locale: string): string | null

NgModule: Module used by getLocaleCurrencySymbol 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 getLocaleCurrencySymbol.
import { LOCALE_ID, NgModule } from '@angular/core';
  • In app.component.ts import getLocaleCurrencySymbol 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.

Return value:
