This is a very insightful article on encapsulation in JavaScript. I appreciate the way you clearly explained the concept and highlighted its importance in writing clean, maintainable, and secure code. Encapsulation is often overlooked, but as you rightly pointed out, it plays a vital role in protecting data and ensuring proper abstraction. The practical examples you provided make the topic much easier to grasp, even for those who may not have encountered it before.
