In this article, we are going to see what is getLocaleWeekEndRange in Angular 10 and how to use it. The getLocaleWeekEndRange is used to get the range of week days for the given locale.

Syntax:

getLocaleWeekEndRange(locale : string): [WeakDay, WeakDay]

NgModule: Module used by getLocaleWeekEndRange is:

  • CommonModule

Approach: 

  • Create an angular app.
  • In app.module.ts, import LOCALE_ID because we need locale to be imported for using get getLocaleWeekEndRange.
import { LOCALE_ID, NgModule } from '@angular/core';
  • In app.component.ts, import getLocaleWeekEndRange and LOCALE_ID.
  • Inject LOCALE_ID as a public variable and write the code for getting first day of week using locale 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:
