Every introductory WebGL tutorial I could find uses utility libraries (*e.g.*, [Sylvester](http://sylvester.jcoglan.com/)) in efforts to make the examples easier to understand. While encapsulating common patterns is desirable when writing production code, I find this practice highly counterproductive to learning because it forces me to learn the utility library first (another layer of abstraction) before I can understand the underlying standard. Even worse when accompanying examples use *minified* JavaScript…

So here’s a simple Hello World in vanilla WebGL with no dependencies and linear control flow. Enjoy.
