👉 The class fluid is a fundamental concept in object-oriented programming, particularly within the context of TypeScript and JavaScript. It represents a collection of classes that can dynamically change their type at runtime, allowing for more flexible and adaptable code. Unlike static classes, which are fixed in type and cannot be instantiated, class fluids can be used to create multiple types of classes from a single base class, each with its own specific properties and behaviors. This dynamic nature enables developers to model complex, evolving systems more effectively, where the exact type of a class might not be known until execution. For example, a class fluid can be used to implement different versions of an interface or abstract class, each tailored to specific scenarios or requirements, without the need for multiple static class definitions.
