require() ?

[Attila Szegedi]

Well, here's my take. I originally implemented the require() function in Rhino, and I also set out - earlier this year - to implement it in Nashorn. However, I quickly run into issues. For Rhino I implemented the CommonJS Require/1.1 specification, but Node happens to significantly deviate from that spec. Picking one over the other would make the other harder to introduce for those people who'd need it; also we'd be stuck having to track and keep that standard up to date. The Node implementation differs significantly, so that trying to create a unified implementation ended up having an uncomfortable number of "if(useNodeSemantics)" statements in it (I did set out on that path to see where it leads). Finally, we decided to provide neither implementation as a built-in, and restrict ourselves to be a vanilla ECMAScript runtime instead. We have an in-house port of Node, and people who work on it provide require() in it.
