전 글에도 적었지만 swc css minifier 성능 최적화를 하다가 DoD 라는 걸 알게 됐다. 힙 할당을 늘렸는데 성능이 엄청 올라간 걸 보고, ES minifier에도 적용해보고 싶어졌다. 물론 지금 당장 적용할 순 없는 게, SWC의 ES 모듈들은 다운스크림이 너무 많아서 그 정도 규모의 breaking change를 자주 만들긴 힘들다. 그리고 제일 문제인 건 이미 배포된 Wasm 플러그인들이고...

나중에 TS 4.9 지원하면서 AST 호환성 깰 때 같이 머지하려고 ES AST를 DoD를 고려하면서 바꿨고, 벤치마크에 필요한만큼만 패치를 해봤다. 벤치마크 결과는 다음과 같다.

3% ~ 23%면 진짜 무지막지하게 큰 숫잔데, 진짜 날로 먹은 기분이다. 지금 당장 적용할 수 있는 건 아니지만 난 DoD를 찬양하기로 했다.

글 마무리 짓는 건 항상 어려운데 그냥 내가 DoD를 공부할 때 쓴 자료들 링크 남기고 끝내겠다.
