Overview

The challenge

Users should be able to:

• View the optimal layout for the app depending on their device's screen size
• See hover states for all interactive elements on the page
• Create, Read, Update, and Delete comments and replies
• Upvote and downvote comments
• Bonus: If you're building a purely front-end project, use localStorage to save the current state in the browser that persists when the browser is refreshed.
• Bonus: Instead of using the createdAt strings from the data.json file, try using timestamps and dynamically track the time since the comment or reply was posted.

What I learned

From this project, i learned a lot about how does TypeScripts work and it's making me get used to it. But the most important lesson that i learnt is how does a reference type variable works such and built a recursive function to manipulate the origin object.

export function deleteComment(comments: Comment[], id: number) {
  for (let i = 0; i < comments.length; i++) {
    const comment = comments[i];
    if (comment.id === id) {
      comments.splice(i, 1);
      return true;
    }
    if (comment.replies && comment.replies.length > 0) {
      if (deleteComment(comment.replies, id)) {
        return true;
      }
    }
  }
  return false;
}

Continued development

In the future, i would like to improve this project by making a backend for this project using MongoDB, ExpressJS, and NodeJS so it can store the comment that has been published.
