How to use css selector with class prefix by dojo?

Question

Assume there are following divs

<div class="group1 section1" />
<div class="group1 section2" />
<div class="group1 section3" />
<div class="group1 section4" />

<div class="group2 section1" />
<div class="group2 section2" />
<div class="group2 section3" />
<div class="group2 section4" />

Now I have to select all 4 group 1 divs by Dojo, how to work this out

Answer 1

Use dom.query('.group1');

require([
    'dojo/query'
    'dojo/dom',
    'dojo/domReady!'
], function (dom) {
    var group1 = dom.query('.group1');
});
