The WebGL2RenderingContext.getIndexedParameter() method of the WebGL 2 API returns indexed information about a given target.
any gl.getIndexedParameter(target, index);
targetGlenum specifying the target for which to return information. Possible values: gl.TRANSFORM_FEEDBACK_BUFFER_BINDING: Returns a WebGLBuffer.gl.TRANSFORM_FEEDBACK_BUFFER_SIZE: Returns a GLsizeiptr.gl.TRANSFORM_FEEDBACK_BUFFER_START: Returns a GLintptr.gl.UNIFORM_BUFFER_BINDING: Returns a WebGLBuffer.gl.UNIFORM_BUFFER_SIZE: Returns a GLsizeiptr.gl.UNIFORM_BUFFER_START: Returns a GLintptr.indexGLuint specifying the index of the target that is queried.Depends on the requested information (as specified with target).
var binding = gl.getIndexedParameter(gl.TRANSFORM_FEEDBACK_BUFFER_BINDING, 0);
