<button id="addCommentBtn">Enter</button>
<div class="comments" id="commentsContainer">
<!-- Comments will be displayed here -->
</div>
<script>
// Initialize an empty array to store comments
let comments = [];
// Function to add a new comment
function addComment() {
const commentInput = document.getElementById("commentInput");
const commentText = commentInput.value;
if (commentText.trim() !== "") {
comments.push(commentText);
// Save the updated comments array to localStorage
localStorage.setItem("comments", JSON.stringify(comments));
// Update the comments on the page
displayComments();
// Clear the input field
commentInput.value =

Like this?
let comments = JSON.parse(localStorage.getItem('comments')) || [];
// Function to add a new comment to the array and update localStorage.
function addComment(comment) {
comments.push(comment);
localStorage.setItem('comments', JSON.stringify(comments));
}
// Example of adding a new comment.
const newComment = "This is a new comment!";
addComment(newComment);
// To retrieve comments:
const retrievedComments = JSON.parse(localStorage.getItem('comments'));
console.log(retrievedComments); // This will log all the saved comments.
