Apprendre Why ES6 Classes? | ES6 Class Fundamentals

Before ES6, JavaScript relied on prototype-based syntax to create objects and share methods between them. While this approach is flexible, it can make your code harder to read and maintain, especially as applications grow. Prototype-based object creation often results in scattered method definitions and less intuitive code structure. This can be confusing for developers who are new to JavaScript or those coming from class-based languages like Java or C#. ES6 classes were introduced to address these issues, providing a clear and consistent way to define objects and their behavior. With ES6 classes, you gain improved code clarity, better organization, and a more familiar syntax for structuring your code.

// Prototype-based syntax
function Animal(name) {
  this.name = name;
}
Animal.prototype.speak = function() {
  return this.name + " makes a noise.";
};

// ES6 class syntax
class AnimalClass {
  constructor(name) {
    this.name = name;
  }
  speak() {
    return this.name + " makes a noise.";
  }
}
