How to Create a Single Button to Toggle Text Color in JavaScript

Creating interactive web applications can be an exciting venture, especially when you get to play around with colors and designs. If you've ever found yourself wanting to change text colors with just a click, then you’re in the right place! In this guide, we’ll address a common question: How can I create one button to change the color of a text and then back to the default color? Let’s dive into the solution that simplifies this with a toggle approach.

The Problem

Initially, you may have set up multiple buttons for changing text colors—one for applying a new color and another for reverting back to the original. However, it can be more efficient and user-friendly to have a single button that toggles between two colors.

Imagine your HTML structure includes the following:

The goal here is to condense the functionality of those two buttons into one.

The Solution

To achieve this with just one button, we will use the JavaScript method classList.toggle(). This method allows us to add a class to an HTML element if it doesn’t have it and remove it if it does. Essentially, it helps us switch between two states effortlessly.

Step-by-step Breakdown

HTML Structure: Start with your basic HTML setup, including a header for your text and a single button to toggle the color.
