Note

This guide provides a complete exploration of JavaScript's pure language concepts, from fundamentals to advanced topics. This covers core mechanisms, advanced patterns, functional programming paradigms, metaprogramming capabilities, type systems, language specification details, and concurrency models - essential knowledge for understanding JavaScript at a deep level.

Course Structure

Core Fundamentals

1. Basic Concepts - Variables, data types, operators, and basic syntax
2. Core Language Features - Scope, closures, hoisting, and execution context
3. Advanced Functions - Function types, closures, and advanced patterns
4. Objects and Prototypes - Object-oriented programming and prototype chains

Modern JavaScript

5. Asynchronous Programming - Promises, async/await, and event handling

Advanced Language Concepts

6. Error Handling - Custom errors, error propagation, and defensive programming
7. Memory Management - Garbage collection, memory leaks, and optimization
8. Metaprogramming - Reflect, Proxy, Symbols, and advanced patterns
9. Functional Programming - Pure functions, immutability, functors, and monads

Language Internals

10. Language Specification - ECMAScript spec, engines, and implementation details
11. Advanced Type System - Type coercion, abstract operations, and custom validation
12. Concurrency Models - Event loop, Web Workers, and parallel processing

Learning Path

This guide is structured to build knowledge progressively:

• Start with Core Fundamentals (Sections 1-4) to understand JavaScript's basic building blocks
• Move to Modern JavaScript (Section 5) to grasp asynchronous patterns
• Explore Advanced Concepts (Sections 6-9) to master sophisticated programming patterns
• Dive into Language Internals (Sections 10-12) to understand how JavaScript works under the hood
