The button element is used to create a clickable button.
Add a button element with the text Submit below the input element. The default behavior of clicking a form button without any attributes submits the form to the location specified in the form's action attribute.
Your button element should have an opening tag. Opening tags have this syntax: <elementName>.
assert(document.querySelector('button'));
Your button element should have a closing tag. Closing tags have a / just after the < character.
assert(code.match(/<\/button\>/));
Your button element's text should be Submit. You have either omitted the text or have a typo.
assert(document.querySelector('button').innerText.toLowerCase() === 'submit');
Your button element should be below the input element. You have them in the wrong order.
const collection = [...document.querySelectorAll('input, button')].map(
(node) => node.nodeName
);
assert(collection.indexOf('INPUT') < collection.indexOf('BUTTON'));
