--description--

Give each th element a span element with the class set to sr-only and the following text, in order: 2019, 2020, and 2021.

--hints--

Each of your th elements should have a span element.

js
const ths = [
  ...document.querySelectorAll('table')?.[1]?.querySelectorAll('th')
];
ths?.forEach(th => {
  assert.lengthOf(th?.children, 1);
  assert.strictEqual(th?.children?.[0]?.localName, 'span');
});

Each of your new span elements should have the class attribute set to sr-only.

js
const ths = [
  ...document.querySelectorAll('table')?.[1]?.querySelectorAll('th')
];
ths?.forEach(th => {
  assert.isTrue(th?.children?.[0]?.classList?.contains('sr-only'));
});

Your first span element should have the text 2019.

js
const table = document.querySelectorAll('table')?.[1];
const th = table.querySelectorAll('th')?.[0];
assert.strictEqual(th.children?.[0]?.textContent.trim(), '2019');

Your second span element should have the text 2020.

js
const table = document.querySelectorAll('table')?.[1];
const th = table.querySelectorAll('th')?.[1];
assert.strictEqual(th?.children?.[0]?.textContent.trim(), '2020');

Your third span element should have the text 2021.

js
const table = document.querySelectorAll('table')?.[1];
const th = table.querySelectorAll('th')?.[2];
assert.strictEqual(th?.children?.[0]?.textContent.trim(), '2021');

Your td element should be empty.

js
const table = document.querySelectorAll('table')?.[1];
const td = table.querySelectorAll('td')?.[0];
assert.strictEqual(td?.textContent.trim(), '');
assert.lengthOf(td?.children, 0);
