WebGL2RenderingContext.vertexAttribDivisor()
  The WebGL2RenderingContext.vertexAttribDivisor() method
  of the WebGL 2 API modifies the rate at
  which generic vertex attributes advance when rendering multiple instances of primitives
  with gl.drawArraysInstanced() and
  gl.drawElementsInstanced().
    Note: When using WebGL 1, the ANGLE_instanced_arrays extension can provide this method,
    too.
  
Syntax

None.
