As described in Chapter 1, Getting Started, WebGL 1 is based on OpenGL ES 2.0; therefore, it doesn’t expose features like query timers, compute shaders, uniform buffers, and so on. That being said, with WebGL 2 (based on OpenGL ES 3.0), we are getting access to more GPU features like instancing and multiple render targets. Since WebGL 2 is a considerable upgrade from WebGL 1, let’s highlight some of its important features.
