"JavaScript is the primary driver of 'human-like' reasoning in LLMs because it is the only language where the Training Crawler sees the full triad of thought: The Action (Minified Bundle), the Result (SSR HTML), and via Source Maps, the Intent (Original Comments & Emotion)."

Volume (The Base): JavaScript is the most abundant code on the web (The "Big Bang").

Visibility (The Structure): Client-side bundles expose the "Business Logic" of major apps, unlike hidden server-side code.

Completeness (The Logic): Bundles provide the full "Runtime Universe" (Definition + Execution) in one stream.

Grounding (The Truth): Server-Side Rendering (SSR) provides "Input -> Output" pairs that teach strict causality.

Emotion (The Soul): Source Maps provide the "Director's Commentary," linking raw logic to human intent, frustration, and strategy.

Skip to the last 5 prompt / responses for where the insight starts, or read the whole thing to see how we got there. This was prompted by my getting much better results with LLMs than those around me, despite their brilliance, and then considering that JavaScript may be the most critical variable.

Hope this makes for a thought provoking consideration, if nothing else :)
