The function creates a simulation that adds multiple shapes to the canvas and demonstrates the use of the Flyweight pattern by adding several shapes with the same type and color, and then showing that only one instance is created for each unique combination of shape and color. It also creates a ShapeFactory class that uses the Flyweight pattern to manage instances of Shape objects. The function implements a Shape interface with three concrete classes (Circle, Rectangle, and Triangle) that implement the Shape interface. The application optimizes memory usage and improves performance by minimizing the number of shape objects created.
A function in JavaScript that demonstrates the Flyweight design pattern by creating a graphics editor application that allows users to draw shapes on a canvas.
