Not sure what this challenge is looking for

Not really sure what this challenge is looking for. I would have thought that the value input would be held in the index variable and if the value is either 0,1 or 2 then set the font type to bold and if not it would be normal.

app.js 
const laws = document.getElementsByTagName('li');
const indexText = document.getElementById('boldIndex');
const button = document.getElementById('embolden');

button.addEventListener('click', (e) => {
    const index = parseInt(indexText.value, 10);

    for (let i = 0; i < laws.length; i += 1) {
       let law = laws[i];

       // replace 'false' with a correct test condition on the line below
       if (index <= 2) {

           law.style.fontWeight = 'bold';
       } else {
           law.style.fontWeight = 'normal';
       }
    }
});
index.html 
<!DOCTYPE html>

  </ul>

Hi Martin,

The challenge wants to embolden the list item to the corresponding index. In this case you want to test if i is equal to index.
