Visual Studio Code `jsconfig.json` "module" option

Question

I'm using jsconfig.json to configure Visual Studio code to enable ES6 support in my project. In the compilerOptions node of the config file there is an option called "module" that takes one of four possible values:

1. commonjs
2. amd
3. system
4. umd

I understand that commonjs, amd and umd are JS module systems.

My question is what is the system value? It sounds like a "default, inherit the setting from elsewhere" type of setting but I cannot find any documentation on it.

Answer 1

It's ES6's System module loader, which was removed in 2014.

Here's an example of how it looks like: https://github.com/ModuleLoader/es6-module-loader
