//Html

<article id="mission">
<ul>
<li>
<input type="checkbox" />
<span>밥먹기</span>
</li>
<li>
<input type="checkbox" />
<span>잠자기</span>
</li>
<li>
<input type="checkbox" />
<span>운동하기</span>
</li>
</ul>
</article>

 

//js

// 여기에 코드를 작성해주세요
let mission = document.querySelector('#mission');
let box = document.querySelectorAll('input');

box.forEach(e=>{
e.addEventListener('click',()=>{
if(e.checked == true)
e.nextElementSibling.style.textDecorationLine = "line-through"
else
e.nextElementSibling.style.textDecorationLine = "none"
})
})
