Kotlin documentation:
- plain (default)
- amd: is usually used on the client-side in the browser. The idea behind AMD is to load modules asynchronously, thus improving usability and performance.
- commonjs: is the module system used on the server-side, and in particular with node.js. Node modules all abide by this definition. CommonJS modules can also be used in the browser via Browserify.
- umd: tries to unify both models allowing these to be used either on the client or server
