Enter ES6 Classes: Syntactic Sugar for Prototypes
Enter ES6 Classes: Syntactic Sugar for Prototypes 관련
You see, in 2015, JavaScript developers recognized that using prototypes and constructor functions directly to achieve class-like patterns could become verbose and less straightforward to manage as applications grew. Therefore, they introduced the class syntax in ECMAScript 2015 (ES6).
Classes in JavaScript provide a much cleaner and more familiar way to create object blueprints and set up inheritance. But here’s the super important thing to remember: JavaScript classes are still built on top of prototypes. They don't fundamentally change how JavaScript OOP works. They are just syntactic sugar – a nicer, easier way to write code that's still using prototypes behind the scenes.
In the next section, we'll see how to rewrite our Person, DeveloperPerson, and JavaScriptDeveloperPerson examples using the new class syntax, and you'll see how much cleaner and more class-like (pun intended) it feels, while using the power of JavaScript prototypes.
