A better approach is to re-use arrays instead of creating intermediate ones, which is what gl-matrix[1] advocates. Each tween might still need its own matrix instance for start and end points, but at least these are not created per tick. A similar approach is to use a "pool" of arrays[2] which allows you to re-use them without having to manually keep track of the temporary arrays.

> Until you can do matrix/vector math using hardware, webGL is pretty much useless. Modern matrix libraries like glMatrix https://github.com/toji/gl-matrix use typed arrays effectively to do very fast matrix and vector math in JS. A modern JS engine can transform such code into something very efficient, more than fast enough to do things like even first person shooters.
