JavaScript में अंतिम कोड

यहाँ अंतिम संस्करण है जो हमें मिलना चाहिए:

body {
	text-align: center;
}

#input, #list {
	display: inline-block;
}

#list {
	padding: 0;
	list-style-type: none;
}
#list span {
	margin-right: 5px;
}
#list .remove, #list .mark {
	color: blue;
	cursor: pointer;
}
#list .remove:hover, #list .mark:hover {
	text-decoration: underline;
}

#list .done .task {
	text-decoration: line-through;
}

<div id="wrapper">
	<input id="input"><br>
	<ul id="list"></ul>
</div>

let input = document.querySelector('#input');
let list = document.querySelector('#list');

input.addEventListener('keypress', function(event) {
	if (event.key == 'Enter') {
		let li = document.createElement('li');
		
		let task = document.createElement('span');
		task.classList.add('task');
		task.textContent = this.value;
		task.addEventListener('dblclick', function() {

			let self = this;
			edit.addEventListener('keypress', function(event) {
				if (event.key == 'Enter') {
					self.textContent = this.value;
				}
			});
		});
		li.appendChild(task);
		
		let remove = document.createElement('span');
		remove.textContent = 'हटाएं';
		remove.classList.add('remove');
		remove.addEventListener('click', function() {
			this.parentElement.remove();
		});
		li.appendChild(remove);
