--description--

Ora rimuoviamo un elemento HTML dalla pagina usando jQuery.

jQuery ha una funzione chiamata .remove() per farlo

Rimuovi l'elemento #target4 dalla pagina utilizzando la funzione .remove().

--hints--

Dovresti usare jQuery per rimuovere l'elemento target4 dalla tua pagina.

assert(
  $('#target4').length === 0 && code.match(/\$\(["']#target4["']\).remove\(\)/g)
);

Dovresti usare solo jQuery per rimuovere questo elemento.

assert(
  code.match(/id="target4/g) &&
    !code.match(/<!--.*id="target4".*-->/g) &&
    $('#right-well').length > 0
);
