Open JS Node.js Application Developer (JSNAD) Node.js development demands comfort with asynchronous JavaScript patterns—callbacks, promises, and async/await syntax form the foundation here. JSNAD expects you to already think in terms of event loops and non-blocking I/O. You’ll need working knowledge of CommonJS modules, npm workflows, and basic stream concepts before the exam challenges you with production-grade server architecture and middleware design decisions.
