Stuck on Challenge Task 1 of 1 - Fix DOM Manipulating Code - DOM Scripting Course

Hello,

I'm stuck with the solution of task below. Need to replace 'false' with the right if statement condition.

Many thanks

app.js 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 (false) {
       law.style.fontWeight = 'bold';
   } else {
       law.style.fontWeight = 'normal';
   }
}

});

index.html <!DOCTYPE html> <html> <head> <title>Newton's Laws</title> </head> <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>

Did you try anything yet? Here's some hints:

The code already converts the user input into a number for you. So, how might you use that to construct an expression that compares it to the loop counter?

All you had to do is change the following:

if (false) {

to

if (index === i) {

Once you make that change, you will pass the challenge.
