- 10.01Enterprise Design Patterns: Observer, Event Emitter & Factory Functions4 min
Master modern software design patterns in JavaScript. Implement the Observer pattern, engineer a robust EventEmitter with once/off semantics, and favor factory composition.
- 10.02Metaprogramming: Proxies, Reflect API & Fine-Grained Reactive Traps4 min
Dive into runtime metaprogramming. Intercept low-level object operations using the Proxy constructor, preserve default receiver semantics with Reflect, and build fine-grained reactivity.
- 10.03True Multi-Threading: Web Workers, SharedArrayBuffer & Atomics4 min
Break free from the single-threaded constraint. Offload intensive computations to Web Workers, transfer binary buffers with zero copy, and coordinate memory with SharedArrayBuffer and Atomics.
- 10.04Capstone Project: Production Reactive State Store with Time-Travel & MiddlewareProject4 min
Engineer an enterprise-grade reactive state store from the ground up. Architect immutable updates, selector subscriptions, middleware pipelines, and an undo/redo time-travel history engine.
