How to determine if element attribute exists or not using TestCafe?

Question

I'm using TestCafe and would like to determine if the checkbox element is present or not. In the HTML element, if the checkbox is already checked then the attribute checked exists otherwise not. How do I determine using TestCafe?

I used the function available in TestCafe - .hasAttribute('checked') but the return is undefined.

Here is the HTML code when the checkbox is checked:

<input class="jss1523" tabindex="-1" type="checkbox" data-indeterminate="false" value checked>

Here is the HTML code when the checkbox is unchecked:

<input class="jss1523" tabindex="-1" type="checkbox" data-indeterminate="false" value>

How do I solve this using TestCafe?

For every Dom element which you get with Selector() you can check property checked - https://devexpress.github.io/testcafe/documentation/test-api/selecting-page-elements/dom-node-state.html#members-specific-to-element-nodes

For checkboxes and radio inputs it returns Boolean value (true - if checked, otherwise - false) and for other types of elements return undefined
