JavaScript Variables Explained Clearly: Values, Types, and How Data Really Works

This article is part of the '40 Days of JavaScript' series and focuses on JavaScript variables, how values are stored, and why JavaScript behaves the way it does with data changes. It explains the difference between var, let, and const, assignment vs reassignment, primitive and non-primitive values, and introduces memory concepts that clarify common JavaScript behaviors. The lesson aims for clarity over speed, targeting beginners who need a solid foundation before moving to functions, objects, React state, and debugging. It includes a video tutorial for visual learners.
