Fortunately, with JavaScript, building a word counter can be a straightforward and rewarding project. In this JavaScript tutorial, we’ll explore how to build a word counter using JavaScript, from gathering user input to displaying the word count in a simple and effective manner.

Whether you’re a beginner or an experienced JavaScript developer, this guide will provide you with the tools you need to create a useful and functional word counter for your web applications. We will be implementing CSS to enhance the GUI of our application.

Objectives:

1. To understand the basics of HTML and CSS required to create a simple text input field and display the word count on the screen.

2. To retrieve user input from a text field and store it in an array and count each non-null string in the text using JavaScript.

3. To create an event listener to detect changes in the input field and update the word count in real time.

4. To implement a function that calculates the number of words in the user input, accounting for different edge cases and special characters.

5. To explore different ways of optimizing the word counting function for efficiency and accuracy.

6. Customize the appearance of the word count display, such as font size, color, and formatting.

7. Test the word counter on different types of input and identify potential issues or bugs.
