Notice that everything you've added to the page so far is inside the body element. All page content elements that should be rendered to the page go inside the body element. However, other important information goes inside the head element.
The head element is used to contain metadata about the document, such as its title, links to stylesheets, and scripts. Metadata is information about the page that isn't displayed directly on the page.
Add a head element above the body element.
You have either deleted the body element or it is missing an opening tag or closing tag.
assert(document.querySelector('body') && code.match(/<\/body>/));
Your head element should have an opening tag. Opening tags have the following syntax: <elementName>.
assert(code.match(/\<head\>/));
Your head element should have a closing tag. Closing tags have a / just after the < character.
assert(code.match(/\<\/head\>/));
Your head element should be above the opening body element tag. You have put it somewhere else.
const noSpaces = code.replace(/\s/g, '');
assert(noSpaces.match(/\<\/head\>\<body\>/));
