how to access id using variable in jquery

Question

html :-

<div id="456"></div>

JQuery :-

var myvar = "456";

$('?----myvar-----?').addClass('newclass');

is it Possible to access "id" without writing $('#123'). i want to use id by using variable

FYI, when adding tags, only add the tags that are relevant to the question/issue. This is a pure js/jquery question so I removed the PHP tag. — M. Eriksson

Here is a simple script:

var myvar = '456';
$('#'+myvar).addClass('newclass');

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="456">Test Div</div>
