Full Stack JavaScript Techdegree Student 4,685 PointsI am completely lost, ive tried endless combinations and nothing works, either all list items bold or none of them do
I cant figure out what test condition goes in this if statement. Ive tried all combinations of variables and event targets but all I can get is all list items to bold or none. any help would be appreciated
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 ( ) {
law.style.fontWeight = 'bold';
} else {
law.style.fontWeight = 'normal';
}
}
});

You want to check if the loop index i
matches the value given by the user in the text input, which they've conveniently stored for you in the variable index
.
I hope this helps -- let me know if you get stuck!
