Intension, Extension, and Type Hierarchies
Explore the concepts of intension and extension in object types and understand how type hierarchies, subtyping, and inheritance work. Learn to specialize types by extending features or restricting instances, and grasp single and multiple inheritance along with classification constraints. This knowledge helps you build better object-oriented JavaScript applications with clear type structures.
