Elfenben is a fork of the awesome Lispyscript project

Without the great developers behind Lispyscript, Elfenben would not be possible. The project can be found here.

Lispyscript was inspired by Beating the averages.

Why the name change?

While Lispyscript is awesome I wanted to take the project into a different direction by taking advantage of ES6 and bringing focus on compatibility with Node as opposed to the browser. For browser compatiblity a transpiler like Babel or Typescript can be used.
