Retrieve Weekday Name Using JavaScript

Introduction

In this lab, we will explore how to retrieve the name of the weekday from a given date object using JavaScript. We will use the Date.prototype.toLocaleDateString() method with the { weekday: 'long' } option to get the weekday name. Additionally, we can specify a language-specific name using the optional second argument or use the default locale.

Retrieving Day Name from a Date Object

To retrieve the name of the weekday from a Date object, follow these steps:

1. Open the Terminal/SSH and type node to start practicing coding.
2. Use Date.prototype.toLocaleDateString() with the { weekday: 'long' } option to retrieve the weekday.
3. You can use the optional second argument to get a language-specific name or omit it to use the default locale.

Here's an example implementation:

const dayName = (date, locale) =>
  date.toLocaleDateString(locale, { weekday: "long" });

You can use this function like this:

dayName(new Date()); // 'Saturday'
dayName(new Date("09/23/2020"), "de-DE"); // 'Samstag'

Summary

Congratulations! You have completed the Day Name lab. You can practice more labs in LabEx to improve your skills.
