A comprehensive JavaScript course covering the language's internal mechanics and conceptual foundations. Topics include scope (global, function, and block), closures in depth with practical examples, the difference between var and let, lexical scoping, IIFE patterns, private variables via closures, garbage collection, and how closures behave in asynchronous contexts like setTimeout and fetch. The course uses real-world analogies and step-by-step code walkthroughs to demystify concepts that trip up many developers in interviews and production code.
