# --description--
Dentro do elemento `tbody` , adicione quatro elementos `tr` . Dê aos três primeiros um atributo `class` definido como `data` e ao quarto um atributo `class` definido como `total` .
# --hints--
O elemento `tbody` deve ter quatro elementos `tr` .
```js
const children = [...document.querySelectorAll('table')?.[1]?.querySelector('tbody')?.children];
assert(children?.length === 4);
children.forEach(child => assert(child?.localName === 'tr'));
```
Os primeiros três elementos `tr` devem ter o atributo `class` definido como `data` .
```js
const children = [...document.querySelectorAll('table')?.[1]?.querySelector('tbody')?.children];
children.forEach((child, index) => {
if (index < 3 ) {
assert(child?.classList?.contains('data'));
}
});
```
O quarto elemento `tr` deve ter o atributo `class` definido como `total` .
```js
const children = [...document.querySelectorAll('table')?.[1]?.querySelector('tbody')?.children];
assert(children?.[3]?.classList?.contains('total'));
```
