3. What is the difference between classical inheritance and prototypal inheritance? Class Inheritance: instances inherit from classes (like a blueprint — a description of the class), and create sub-class relationships: hierarchical class taxonomies. Instances are typically instantiated via constructor functions with the new keyword. Class inheritance may or may not use the class keyword from ES6. Prototypal Inheritance: instances inherit directly from other objects. Instances are typically instantiated via factory functions or Object.create(). Instances may be composed from many different objects, allowing for easy selective inheritance.
In JavaScript, prototypal inheritance is simpler & more flexible than class inheritance.
Good to hear: Classes: create tight coupling or hierarchies/taxonomies. Prototypes: mentions of concatenative inheritance, prototype delegation, functional inheritance, object composition.
Red Flags: No preference for prototypal inheritance & composition over class inheritance.
