Full Stack JavaScript Techdegree Student 4,074 PointsBeen stuck on this challenge for a while. I can't figure out why the code below doesn't work. if (index.value = law)
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.value = law) {
law.style.fontWeight = 'bold';
} else {
law.style.fontWeight = 'normal';
}
}
});
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 = i) {
law.style.fontWeight = 'bold';
} else {
law.style.fontWeight = 'normal';
}
}
});

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 ( i === index ) {
law.style.fontWeight = 'bold';
} else {
law.style.fontWeight = 'normal';
}
}
});
