JavaScript Object Architecture: Prototypes, Inheritance, and Classes

JavaScript's inheritance model is unique and often misunderstood. This guide peels back the syntactic sugar of ES6 Classes to reveal the prototypal engine underneath. We analyze the transition from constructor functions to `class` keywords, explore the mechanics of the prototype chain, and implement robust OOP patterns using private fields, mixins, and polymorphism.

JavaScript Concurrency & Architecture: Async, Modules, and Error Handling

Asynchronous programming is the heartbeat of JavaScript. This comprehensive guide dissects the runtime's concurrency model—explaining the Event Loop, Microtasks, and the transition from Callbacks to Async/Await. Beyond logic, we define structural best practices: implementing defensive error handling strategies and organizing codebases using modern ES Modules.

JavaScript Advanced Flows: Iterators, Generators, and Keyed Collections

Standard Arrays and Objects are not always the right tools for the job. This deep dive introduces the specialized efficiency of Maps and Sets, alongside the memory-safety mechanisms of WeakMaps. Furthermore, we deconstruct the Iterator Protocol and Generator functions, empowering you to implement lazy evaluation, custom traversal logic, and infinite sequences.

JavaScript Meta-Programming: Proxies, Reflect, and Dynamic Introspection

Meta-programming is the capability of code to analyze and manipulate its own structure and behavior. This article explores the cutting edge of JavaScript introspection. We dissect the Proxy object—the engine behind modern reactivity systems like Vue 3—and the Reflect API, while drawing hard lines around legacy pitfalls like `eval` and the `with` statement.
