Shorten Your JavaScript Code for Chess Squares with Ease!

In this post, we’ll explore solutions to condense your JavaScript code and improve your workflow.

The Problem

As mentioned, the problem arises when you create individual variables for each chess square. The method you might typically use looks something like this:

While this method works, it results in an excessive amount of code, making your files unnecessarily lengthy and hard to maintain.

The Solution

1. Using a Loop

Instead of declaring each variable manually, you can significantly reduce the number of lines by using a loop. Here's how you can do it:

How It Works:

new Array(64): Creates an array with 64 slots.

map((_, i) => ...): Loops through each index and retrieves the element by its ID, generating the corresponding chess square dynamically.

You can then access any square using its index like this:

2. A Better Approach: Using Parent Elements

While the looping method works, there’s an even better approach that avoids using so many IDs altogether. Instead, consider organizing your chessboard within a parent element.

Corresponding JavaScript Code

Once you have the board structured this way, fetching the squares can be done in one line:

3. Implementing Interactivity

This method not only keeps your code short but also opens up possibilities for interactions. For example, you can add event listeners to each square:

Final Thoughts

By rethinking how you structure your chess game's HTML and JavaScript code, you can streamline your development process and make your code more maintainable. Utilizing loops for array construction and avoiding excessive DOM IDs are techniques that will serve you well beyond this project. Happy coding, and enjoy building your chess game!
