JavaScript’s versatility lies in its ability to handle complex data structures, and at the heart of this capability are objects and prototypes.

In this article, we’ll dive into the practical aspects of JavaScript Objects and Prototypes, unraveling their nuances with straightforward explanations and code examples.

Understanding JavaScript Objects

Objects are the backbone of JavaScript, providing a way to structure and organize data. Think of them as containers that hold key-value pairs, allowing you to represent real-world entities in your code.
