Node.js

Node.js isn't a language - it's a runtime that took JavaScript out of the browser sandbox and dropped it into the server room with filesystem access , raw sockets , and process control. V8 engine stripped of Chrome's chrome , glued to libuv for async I/O , wrapped in C++ bindings that give JS superpowers it was never designed for. Ryan Dahl built it in 2009 and somehow 70% of backend APIs now run JavaScript in places nobody expected a browser language to survive

78 files covering the full Node.js curriculum through a 0x1RIS security lens - dry humor , zero hand-holding , production-ready knowledge
