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 >= 0 && index <= 2) {
law.style.fontWeight = 'bold';
} else {
law.style.fontWeight = 'normal';
}
}
});

What your code seems to do is embolden every list element, but the challenge asks that you embolden the list element that position matches the number entered into the input text field. So if I am a user and I enter 1, then only the second list element should be emboldened. But your for loop cycles through all the list elements and as long as the number I enter in the input text field is between 0 and 2, it emboldens all of the list elements and not just the one I meant to target.
You'll want to change your test condition from (index >= 0 && index <= 2) to (index === i). Once you do that, you should be all set.
