Core Features & Use Cases

• Prototypal Inheritance: Understand and leverage object inheritance through prototypes.
• First-Class Functions & Closures: Utilize functions as values and manage state effectively with closures.
• Dynamic Typing: Embrace and work with JavaScript's flexible type system.
• Use Case: Refactor legacy JavaScript code to be more idiomatic and efficient by applying Eich's design philosophy, leading to more maintainable and performant applications.
