import と require() の違い

CommonJSのモジュール内でrequire()を使ってESMを読み込むこと、 ESMのモジュール内からimportを使ってCommonJSを読み込むことは可能だけど、 CommonJSの中からimportを使うことはできない。 ESMの中であれば例えば import { require } from 'nodejs' とかやれば可能になる。

• CommonJSのモジュール内で require() を使ってESMを読み込むことは可能
• ESMのモジュール内から import を使ってCommonJSを読み込むことは可能
• ESMのモジュール内から require() を使うことは不可能ではない
