What is a key difference between object-oriented languages and non-object-oriented languages?

A key difference between object-oriented languages and non-object-oriented languages lies in the way they organize and structure code. Object-oriented languages use the concept of "objects," which are instances of classes that encapsulate both data and functionality. This means that in an object-oriented language, developers can create models of real-world entities within the code, allowing for a modular design, inheritance, polymorphism, and encapsulation. This approach facilitates code reuse and enhances maintainability by grouping related functionalities and data together.

In contrast, non-object-oriented languages typically rely on procedural or functional paradigms, where the code is structured around functions and procedures. These languages do not inherently support the object-oriented principles of encapsulation and inheritance, leading to a different methodology in organizing and managing code.

Understanding this distinction is crucial, as it impacts how developers approach software design, manage complexity, and scale applications. The encapsulation of state and behavior in objects in object-oriented languages supports more sustainable software development practices and aligns closely with how software applications are often conceptualized in the real world.
