Show HN: The One File I Created for Every Programming Language (10+ Years)

Throughout my career, while exploring different programming languages, I realized that having a quick reference was essential for refreshing my memory on the fly. So I developed a habit: for every new language I learned, I’d build a reference file (like python_reference.py) that documented everything from basic syntax to advanced features. Now, a decade later, these files have become my go-to resource. They’ve helped me study for interviews, revisit old projects after years, and now, in the AI era where generating code in unfamiliar languages is more common than ever, I think they’re more relevant than ever. A concise, straight to the point reference can be the difference between "it works" and "I actually understand why it works." I believe these references will be especially helpful for developers looking to pick up a new language quickly, without having to go through extensive courses or tutorials. I've updated most of the references, added some new ones, an
