// Object Oriented Programming

// There are no dynamic prototypes in candor, but there is a fast-clone
// operation and special method calling syntax to make OOP style programming
// possible if you prefer that style.

// Create a prototype object
Rectangle = {
  getArea: (self) {
    return self.w * self.h
  },
  initialize: (self, w, h) {
    self.w = w
    self.h = h
  }
}

// First create a fast shallow clone of the Rectangle prototype
rect = new Rectangle

// Then initialize it using a one of the functions
rect.initialize(rect, 3, 5)

// Now we can use this object
rect.getArea(rect) // -> 15

// To make calling methods easier, there is special syntax sugar using `:`
// instead of `.` for function calls. It means to call the function with
// whatever is left of the `:` as the first argument.

// The previous two calls can be written as:
rect:initialize(3, 5)
rect:getArea() // -> 15
