How to Dynamically Display Different Texts Based on Browser Language

In today's global environment, creating a user-friendly experience means acknowledging the diversity of languages. If you're working on a web application, offering different content based on the user's browser language is a great way to enhance usability. In this guide, we'll explore how to achieve this using JavaScript.

The Problem

You might be wondering, "How do I display different texts depending on the browser language?" A common approach is to check the user's default language setting and then deliver content accordingly. However, many developers face challenges when implementing this solution. For example, you might have used a switch statement to set the text, but it didn’t work as expected.

Here’s the initial attempt you might have considered:

Despite your efforts, nothing displayed on the screen. So, let's dive into the solution and ensure you can get it right!

The Solution

To properly display text in different languages, it's essential to follow some key steps to ensure your code runs without errors. Below is a structured guide on how to implement this successfully.

Step 1: Retrieve the User's Language

The first thing you need to do is get the user's default browser language. You can accomplish this using the navigator.language property.

Step 2: Simplify the Language Code

Most browser language codes come in a format that includes a region (e.g., en-US). To handle just the language part (like en or es), you'll need to truncate this string.

Step 3: Use a Proper Switch Statement

Now that you have the correct language code, you can use a switch statement to set the text according to the language. Make sure to wrap the case values in quotes:
