files, include, exclude?

• 셋 다 설정이 없으면, 전부 다 컴파일
• files
  • 상대 혹은 절대 경로의 리스트 배열
  • exclude 보다 강함
• include, exclude
  • glob 패턴(.gitignore)
  • include
    • exclude 보다 약함
    • • 같은 걸 사용하면, .ts / .tsx / .d.ts 만 include (allowJS)
  • exclude
    • 설정 안하면 4가지 (node_modules, bower_components, jspm_packages, ) 를 default 로 제외함
    • 은 항상 제외 (include 에 있더라도)
