JavaScript Deep Dive
An exhaustive, engine-level JavaScript masterclass — memory and type coercion mechanics, the prototype chain and `this` binding, the event loop and Promise internals, V8 JIT optimization and garbage collection, and expert design patterns with Proxies.
JavaScript Deep Dive — Module 1: Foundations & Core Engine Mechanics
Primitive vs. reference types and the Stack/Heap split, the ToPrimitive/ToString/ToNumber coercion machinery, execution contexts and hoisting, and closures as a mechanical consequence of the scope chain.
JavaScript Deep Dive — Module 2: Mastering the Prototype Chain & Objects
Property descriptors, `__proto__` vs `prototype`, hand-built prototypal inheritance without `class`, all four `this`-binding rules, and what ES6 classes and private fields actually compile down to.
JavaScript Deep Dive — Module 3: Asynchronous JavaScript & The Event Loop
The Call Stack, Web APIs, Microtask and Macrotask queues; a hand-built mini-Promise implementation; how async/await desugars onto generators; and orchestrating Promise.all/allSettled/race/any correctly.
JavaScript Deep Dive — Module 4: Advanced Performance, Optimization & Memory
V8's JIT pipeline, Hidden Classes and Inline Caches, deoptimization triggers, generational garbage collection, and the four classic memory leak patterns with fixes.
JavaScript Deep Dive — Module 5: Expert Architecture & Design Patterns
Functional programming — immutability, purity, currying, composition; Observer, Singleton, and Factory patterns in modern JS; and metaprogramming a reactive data-binding system with Proxy and Reflect.
