Design Questions

[srikoushik3]

• Why use decorator design pattern?
• Why did you use observer pattern?
  • We wanted the button click event that gets triggered after a user makes an action (buy, sell or skip next day), is only responsible for sending the info to the backend
  • The rendering of the new modified data (stock tables, user tables and profits graphs) is only changed after the backend notifies the frontend (this the button event is not responsible for rendering of the updated data)
