Single Responsibility Principle

The single responsibility principle states that a class, module, or function should have only one reason to change, meaning it should do one thing.

class Animal {
  constructor(name) {
    this.name = name;
  }
 
  nomenclature() {
    console.log(`The name of the animal is ${this.name}`);
  }
}
 
let animal1 = new Animal('Elephant');
animal1.nomenclature(); // The name of the animal is Elephant
 
// Sound class
class Sound {
  constructor(name, soundMade) {
    this.name = name;
    this.soundMade = soundMade;
  }
 
  sound() {
    console.log(`${this.name} ${this.soundMade}s`);
  }
}
 
let animalSound1 = new Sound('Elephant', 'trumpet');
animalSound1.sound(); //Elephant trumpets
 
// Feeding class
class Feeding {
  constructor(name, feedingType) {
    this.name = name;
    this.feedingType = feedingType;
  }
 
  feeding() {
    console.log(`${this.name} is a/an ${this.feedingType}`);
  }
}
 
let animalFeeding1 = new Feeding('Elephant', 'herbivore');
animalFeeding1.feeding(); // Elephant is a/an herbivore
