While this allows for a lot of control over the animation, it can be pretty hard to understand if you’re not familiar with physics involved, and to be truly useful it needs an editor.

So, Elastic is that editor. It provides a way to tweak each parameter, explains what they do, allows to preview the animation in various ways, and generates the code to create that animation.
