• Why is Learning Functional Programming So Damned Hard?
• What Functional Programming Is + Why It Makes You Better
• Why Isn't Functional Programming the Norm? – Richard Feldman
  • 결론; 대세가 될 것이나 시간이 필요
  • 이유; OOP가 그 자체 고유 특성의 우수성때문에 대세가 된 것이 아니기 때문
    • 예를 들어 OOP 고유 특성중 하나인 상속은 OOP에서조차 기피 대상, 대신 compostion 사용. composition은 FP에도 존재
    • 캡슐화 = 정보 은닉 개념 = 모듈화 개념의 다른 버전
  • 그럼 왜 OOP 언어들이 대세인가
    • Killer App; Ruby on Rails나 Wordpress/Drupal의 PHP
    • 거대 업체 지원; Apple(ObjC, Swift), Google(Go), MS(C#)
    • 시스템상 지원; OS/Embedded(C/C++), 브라우저(Javascript)
    • 이런 모든 것의 지원을 받는 경우; Java(Sun)
    • 꾸준한 업데이트; Python
  • 그러나 이들 언어에서도조차도 함수형 프로그래밍 스타일이 점점 유행
