Rhino is an incredible powerful utility, allowing javascript to be included in mods, making KubeJS and others possible. It works very well most of the time, and does what it sets out to do.

However, this mod doesn't conform to any version of the javascript specification, with weird differences in scoping and it often being unclear which features are supported and which are not.

This mod is still far better than similar mods which add support for scripting languages, as being able to use a more mature language like javascript is a giant bonus over crafttweaker's zenscript in my opinion.

This mod is the best available for what it does, it would just be nice if it properly covered at least one version's specification fully.

Description

A fork of Mozilla's Rhino library, modified for use in mods. This library adds JavaScript engine Rhino that supports ES6 and doesn't depend on built-in Nashorn engine that got removed in Java 15.

This mod doesn't do anything on it's own, it's a library used by KubeJS
