can you make classes in javascript code example

Example 1: how to create a class javascript

class Person {
	constructor(name, age) {
		this.name = name;
		this.age = age;
	}
	displayInfo() {
		return this.name + ' is' + this.age + " years old";
	}
}

const Anthony = new Person('Anthony', 32);

Example 2: javascript classes

//use classes by initiating one like so:
class MyClass {
	constructor(FirstProperty, SecondProperty, etcetera) {
    	//The constructor function is called with the new class 
      	//instance's parameters, so this will be called like so:
      	//var classExample = new MyClass("FirstProperty's Value", ...)
      this.firstProperty = FirstProperty;
      this.secondProperty = SecondProperty;
    }
  //creat methods just like functions:
  method(Parameters) {
  	//Code Here
  }
  //getters are properties that are calculated when called, versus fixed
  //variables, but still have no parenthesis when used
  get getBothValues() 
  {
  	return [firstProperty, secondProperty];
  }
}
//Note: this is all syntax sugar reducing the boilerplate versus a
// function-defined object.

Example 3: javascript classes

//private but is a good example
class includes {
    constructor(){}
  
    inculde_apps(file) { 
      var script  = document.createElement('script'); 
      script.src  = "ext/apps/"+file; 
      script.type = 'text/javascript'; 
      document.getElementsByTagName('body').item(0).appendChild(script);
    } 
    
    inculde_scripts(file) { 
      var script  = document.createElement('script'); 
      script.src  = "ext/scripts/"+file; 
      script.type = 'text/javascript'; 
      document.getElementsByTagName('body').item(0).appendChild(script);
    } 
    
    inculde_css(file) { 
        var script  = document.createElement('link'); 
        script.rel  = "stylesheet"; 
        script.type = 'text/css'; 
        script.href = "css/"+file;
        document.getElementsByTagName('head').item(0).appendChild(script);
    }
  }
