Creating a viewer or a modeler

Hello. I am new to the forum.

I started studying and i am stuck in a newbie question.

Comparing viewer and modeler basic examples i do not get why in one case a viewer is created and a modeler in the other:

// code from viewer example:

      // viewer instance
      var bpmnViewer = new BpmnJS({
        container: '#canvas'

// code from modeler example:

      // modeler instance
      var bpmnModeler = new BpmnJS({
        container: '#canvas',
        keyboard: {
          bindTo: window

thery are both new BpmnJS objects, where do i tell to create a viewer explcitly?
