<ul>
<li>An object in motion tends to stay in motion, unless acted on by an outside force.</li>
<li>Acceleration is dependent on the forces acting upon an object and the mass of the object.</li>
<li>For every action, there is an equal and opposite reaction.</li>

54,967 PointsThe goal is to "embolden the list item with the corresponding index"
The index entered by the user is provided as:
const index = parseInt(indexText.value, 10);
After this the list items are looped through using index i
So if i matches the index entered by the user the list item should be emboldened.

54,967 PointsClose. laws[i] is an element. You want to use the index of that element which is just i
Also you need a comparison operator instead of the assignment operator.

Full Stack JavaScript Techdegree Student 9,620 Pointsconst 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= laws[i]) {
law.style.fontWeight = 'bold';
} else {
law.style.fontWeight = 'normal';
}
}
});
i am close ??

Full Stack JavaScript Techdegree Student 9,620 Pointsomg.. i got it finally.. ```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';
}
}
});``` thank youu

54,967 PointsYeah. It's one of those challenges that once you see it you are surprised at how much easier it is than you originally thought.
