CommonJS CommonJS — require() works on every Node.js version
typings ships CommonJS only. require("typings") works everywhere. import "typings" 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.
Deprecated: Typings is deprecated in favor of NPM @types -- see README for more information
