Which of the following is a characteristic of JavaScript?

JavaScript is indeed characterized as an object-oriented programming language. This means it supports the principles of object-oriented programming (OOP), which includes concepts like encapsulation, inheritance, and polymorphism. In JavaScript, objects can be created and manipulated using constructors, prototypes, and classes, enabling developers to create reusable and organized code.

This object-oriented nature allows for building complex applications where related data and functions can be encapsulated within objects, making them easier to manage and scale. The flexibility of JavaScript to support both object-oriented and functional programming paradigms further enhances its utility in web development.

In contrast, the other choices do not accurately reflect JavaScript's characteristics. JavaScript is not limited to mobile applications; it is primarily associated with web development for creating interactive content in browsers. It also does not primarily focus on database management; database interactions in web applications are typically handled by other technologies or frameworks. Additionally, JavaScript is a cross-platform language and can run in various environments, not just limited to the Windows operating system. This broad compatibility is one of its strengths, allowing it to be used in diverse scenarios across different platforms.
