Angular10 getLocaleDayNames() Function

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

The getLocaleDayNames is used to get days of the week for the given locale.

Syntax:

getLocaleDayNames(
             locale: string, 
             formStyle: FormStyle, 
             width: TranslationWidth
             )

NgModule: Module used by DayNames 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 getLocaleDayNames.

import { LOCALE_ID, NgModule } from '@angular/core';

• In app.component.ts import FormStyle,getLocaleDayNames, TranslationWidth and LOCALE_ID
• inject LOCALE_ID as a public variable and write the code for getting days 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 locale code with rules.
• formStyle: The form style in which days are to be shown
• width: The total width taken.

Return value :

• array: an array of day name.
