WebGL2RenderingContext

trait WebGL2RenderingContext extends Object with WebGLRenderingContext

The WebGL2RenderingContext interface provides the OpenGL ES 3.0 rendering context for the drawing surface of an HTML <canvas> element.

WebGL 2 is an extension to WebGL 1. The WebGL2RenderingContext interface implements all members of the WebGLRenderingContext interface. Some methods of the WebGL 1 context can accept additional values when used in a WebGL 2 context. You will find this info noted on the WebGL 1 reference pages.
