A great KJS addon.

There is one thing which makes this stand out well, even when comparing against KJS: it has great documentation.

This contributes greatly to the developer experience of using this mod in your TFC modpacks. It provides builders for many TFC's blocks such as the plants and great utility features such as bindings for TFC classes, rock layer editing (I don't lean too hard on KJS, preferring Java and core mods for pack development, unless its the easiest option, and this frankly is the easiest way to add custom rock types.) and advanced features like "tree solving" (to create the nbt files TFC uses for trees in forests).

This is a one man project, there are typos, mistakes, and so on and generally the dev is accessible and kind when issues are reported to them.

Its inclusion of simpler features like ways to create TFC data and recipe types, makes it useful for users that are not knowledgeable in datapacks to be able to create stuff for their TFC modpacks.
