JavaScript has evolved into a language capable of handling realtime 3D graphics, via WebGL, and computationally intensive tasks such as physics simulations. These types of applications demand high performance vector and matrix math, which is something that JavaScript doesn't provide by default. glMatrix to the rescue!
glMatrix is designed to perform vector and matrix operations stupidly fast! By hand-tuning each function for maximum performance and encouraging efficient usage patterns through API conventions, glMatrix will help you get the most out of your browser's JavaScript engine.

For a tutorial, see the "Introducing glMatrix" section of Introduction to Computer Graphics by David J. Eck
For a babel plugin to make writing the API nicer, see babel-plugin-transform-gl-matrix
Regarding the current performance in modern web browsers, calling glMatrix.setMatrixArrayType(Array) to use normal arrays instead of Float32Arrays can greatly increase the performance.
