The code inside the <code> tag has inconsistent indentation. The opening line starts on line 35, but the function code on lines 36-38 has extra leading whitespace that will be copied when users click the copy button. Consider removing the extra indentation to provide cleaner copied code, or adjust the indentation to be consistent with typical JavaScript formatting.

The clipboard API usage lacks error handling. If the clipboard write fails (e.g., due to browser permissions or HTTPS requirement), the promise rejection is not caught, which could lead to unhandled promise rejections. Consider adding a .catch() handler to provide user feedback when copying fails.

Suggested change

setTimeout(() => (button.textContent = 'Copy'), 2000);
}).catch(() => {
button.textContent = 'Failed!';
setTimeout(() => (button.textContent = 'Copy'), 2000);

The .code-block class is defined twice in this file (lines 36-38 and lines 68-70). The first definition sets margin-top: 20px and the second sets position: relative. These should be combined into a single rule block to avoid confusion and improve maintainability.

This change downgrades cz-conventional-changelog from ^3.3.0 to ^3.0.1. Unless there's a specific reason for this downgrade (such as compatibility issues), it's generally better to keep dependencies at their latest compatible versions to benefit from bug fixes and improvements. Please verify if this downgrade is intentional.

This change downgrades gitbook-plugin-exercises from ^3.0.0 to ^1.0.0. This is a major version downgrade that could remove important features or break existing functionality. Please verify if this downgrade is intentional and ensure all dependent code remains compatible with version 1.0.0.

This change upgrades honkit from ^4.0.4 to ^6.1.4, skipping version 5 entirely. This is a major version upgrade that may include breaking changes. Please ensure all honkit plugins and configurations are compatible with version 6.1.4, and test the build thoroughly.
