Oct 20, 2024 · JavaScript is unique in that it can support both class-based OOP (introduced in ES6) and prototype-based OOP (the original way JavaScript handled OOP). This blog will dive into key OOP concepts like first-class functions, first-class instances, inheritance, polymorphism, encapsulation, and abstraction using both approaches. 1. First-Class Functions
