CommonJS CommonJS — require() works on every Node.js version

babel-preset-jest ships CommonJS only. require("babel-preset-jest") works everywhere. import "babel-preset-jest" also works because Node.js and Bun can import CommonJS from ES modules, but only the default export is guaranteed; named imports depend on Node's static analysis of the module.
