Have you tried using [Google](//www.google.com/search?q=js+document.getElementById.bind%28document%29%3B) or reading the [documentation](//developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Function/bind)? – Sebastian Simon Feb 20 '23 at 17:57

1Please be more specific what part you don't understand. Is it the `let`? The `$`? The `=`? The `document.getElementById`? The `.bind(document)`? – Raymond Chen Feb 20 '23 at 18:39
