Refactor code structure and add highlighting features
gandalf.js
• Reorganized and moved utility function declarations throughout the file • Added hljs syntax highlighting initialization in preInit function • Added mermaid diagram initialization with startOnLoad configuration • Refactored markdown parsing logic and cleaned up variable assignments
Multiple duplicate and seemingly random constant declarations are scattered throughout the code without clear purpose or usage. These appear to be test/example code that should not be in production.

Missing function declarations and incomplete code structure. The getMarkdownParser function declaration is missing, and convertMarkdowns function is referenced but not properly defined.

The impress.addPreInitPlugin call that registers the plugin is removed, which would break the plugin's functionality entirely.

✅ Add missing plugin registrationSuggestion Impact:The suggestion was implemented by adding the missing impress.addPreInitPlugin(preInit, 1) call at line 171 in the commit
code diff:
+ impress.addPreInitPlugin( preInit, 1 );
The function call is missing from the new code. This will prevent the plugin from being registered and initialized properly, breaking the entire functionality.
[To ensure code accuracy, apply this suggestion manually]
Suggestion importance[1-10]: 10
__
Why: The suggestion correctly identifies that the call to impress.addPreInitPlugin(preInit, 1) was removed in the PR. This line is critical for registering the plugin with impress.js, and its absence will break the plugin's functionality entirely.

Remove redundant ternary operator
This ternary operator is redundant since the comparison already returns a boolean. The expression number > 0 directly evaluates to true or false, making the ternary unnecessary.
-const isPositive = number > 0 ? true : false;+const isPositive = number > 0;

Why: The suggestion correctly identifies a redundant ternary operator. The expression number > 0 already evaluates to a boolean, so simplifying it improves code conciseness and readability.
