Why TypeScript classes are a poor option for representing data

• Why TypeScript classes are a poor option for representing data
  • Example Model
  • JSON format
  • Data structure is as important as data content
  • Problems with classes as data models
    • They are incompatible with declarative syntax
    • They break type safety!
    • They promote mutation
• Decorators to the rescue cause even more problems
