Javascript Classes Development Tutorials, Guides & Insights

Methods can be added to a class by defining functions within the class body. These methods become part of the prototype and are shared among all instances of the class.

class Animal {
  constructor(type, name) {
    this.type = type;
    this.name = name;
  }

  speak() {
    console.log(`${this.name} makes a noise.`);
  }
}

const dog = new Animal('Dog', 'Buddy');
dog.speak(); // Output: Buddy makes a noise.
