A class includes properties and functions. These are the members of the class. A class's functions are similar to regular JavaScript functions and a class's functions are only affiliated with their class. These are the class's member functions. One of the member functions is special: the constructor function. Here is an example class that constructs airplanes:

  class Airplane {
    var model: int;
  
    function Airplane() {
      model = 767;
    }
  } 
A class's constructor function has the same name as its class. All airplanes instantiated using the Airplane class will be 767:

  var firstJet : Airplane;
  var secondJet : Airplane;
  firstJet = new Airplane();
  secondJet = new Airplane();
