SharedArrayBuffer

SharedArrayBuffer is similar to ArrayBuffer, in a way that it can be used to create views on shared memory, so that multiple threads can read and write the same data in memory. Unlike an ArrayBuffer, a SharedArrayBuffer cannot become detached.

APIs accepting SharedArrayBuffer objects:

-WebGLRenderingContext.bufferData()

-WebGLRenderingContext.bufferSubData()

-WebGL2RenderingContext.getBufferSubData()
