The short version

  • Each has a real cost: Angular written for TypeScript, so a plain JavaScript project takes on a compiler step to use it as intended; Flask requires manual configuration of many common features like authentication, ORM, and admin panels
  • They diverge on capability: Angular covers Component-based architecture, Flask covers Lightweight framework.
