Experience
Vectrix Matrices
https://github.com/nphyx/vectrixVectrix is a matrix math library for JavaScript that allows the developer to make conscious tradeoffs between performance, flexibility, and expressiveness.
It implements functional programming principles around a highly optimized set of core functions, with interoperable object-oriented wrappers for ease of use in non-performance-critical situations.
Vectrix aims to be a powerful middle ground between less ergonomic high-performance libraries and more expressive high-level libraries whose performance wasn't suitable for computationally intensive applications.
I created the matrices module and accompanying JSDoc documentation with the rest of the library.
