What is the equivalent of this mad jQuery selector?

I'm trying to convert some jQuery into vanilla JavaScript, but this one just stumped me:

$('<span>[<a href="#" id="addlink">Add</a>]</span>')

The Vanilla Javascript approach for the same could also be achieved using setAttribute() , createTextNode() and appendChild() as follows. Just another way to do this.

const span = document.createElement("span");
const a = document.createElement("a");
a.setAttribute("href", "#");
a.setAttribute("id", "addlink");

const text = document.createTextNode("Add");

a.appendChild(text);
span.append("[", a, "]");

document.body.appendChild(span);
<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
  </head>
  <body>
    <script src="./script.js"></script>
  </body>
</html>

It's not a selector, it creates the DOM elements from this markup and wraps it in a jQuery object. See the docs.

const $el = $('<span>[<a href="#" id="addlink">Add</a>]</span>');
console.log( $el.html() );
$("body").append( $el );
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

So the vanilla equivalent would be

const span = document.createElement("span");
const a = document.createElement("a");
a.href = "#";
a.id = "addlink";
a.textContent = "Add";
span.append( "[", a, "]" );

document.body.append( span );
