Write ten different classes in JavaScript

JavaScript is a popular programming language that can be used to write various types of programs and applications. In JavaScript, classes are used to create objects and simulate real-world concepts. In this article, I will introduce ten different JavaScript classes, each with its specific purpose and functionality.

    this.age = age;
    this.gender = gender;
  }
  
  getName() {
    return this.name;
  }

    return this.age;
  }
}

}

6. Shape class

The Shape class is a class used to create shape objects. It contains some properties, such as type, size and color, and provides some methods, such as getting type, calculating area, etc.

class Shape {
  constructor(type, size, color) {

    this.size = size;
    this.color = color;
  }
  
  getType() {
    return this.type;
  }
  
  getSize() {
    return this.size;

    return this.color;
  }
  
  calculateArea() {
    // code to calculate area
  }
}

7. Movie class

The Movie class is a class used to create movie objects. It contains some attributes, such as name, director and starring, and provides some methods, such as getting the name, getting the starring, etc.

class Movie {
  constructor(title, director, actors) {
    this.title = title;
    this.director = director;
    this.actors = actors;
  }
  
  getTitle() {
    return this.title;
  }
  
  getDirector() {
    return this.director;
  }
  
  getActors() {
    return this.actors;
  }
}

8. Employee class

class Employee {
  constructor(name, id, jobTitle) {
    this.name = name;
    this.id = id;
    this.jobTitle = jobTitle;
  }
  
  getName() {
    return this.name;
  }
  
  getId() {
    return this.id;
  }
  
  getJobTitle() {
    return this.jobTitle;
  }
}

9. Computer class

The Computer class is a class used to create computer objects. It contains some attributes such as brand, model and operating system, and provides some methods such as getting brand, getting model, etc.

class Computer {
  constructor(brand, model, os) {
    this.brand = brand;
    this.model = model;
    this.os = os;
  }
  
  getBrand() {
    return this.brand;
  }
  
  getModel() {
    return this.model;
  }

The above are ten different JavaScript classes, each class has its specific purpose and function. These classes can be used to create various types of objects and provide many convenient methods to make code writing more concise and efficient. Whether you are developing web pages or applications, JavaScript classes are very useful tools and you should use them flexibly in your daily programming work.
