How do i do this

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

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 (false) {

law.style.fontWeight = 'bold';
} else {
law.style.fontWeight = 'normal';
}
}
});
```
index.html
```<!DOCTYPE html>
<html>
<title>Newton's Laws</title>
<body>
<h1>Newton's Laws of Motion</h1>
<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>
</ul>
<input type="text" id="boldIndex">
<button id="embolden">Embolden</button>
<script src="app.js"></script>
</body>
</html>
```

In this challenge you need to change the false with the condition of:

if the entered number is equal to the iterated number of list items, set the weight to bold.

So that is:

if the index is equal to the list item number, set the weight to bold

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

const index = parseInt(indexText.value, 10);  // This is our input field

for (let i = 0; i < laws.length; i += 1) {  // This is the iteration through the list items
let law = laws[i];

if ( i === index ) {  // If our input field is equal to the iterated list item

law.style.fontWeight = 'bold';  // Set the weight bold
} else {
law.style.fontWeight = 'normal';
}
}
});
```
