When a comment's delete button is clicked by the commenter, the Comments component will call the deleteComment method to fetch the uncomment API, and update the comments along with the comment count when the comment is successfully removed from the server.
mern-social/client/post/Comments.js:
deleteComment = comment => event => { const jwt = auth.isAuthenticated() uncomment({ userId: jwt.user._id }, { t: jwt.token }, this.props.postId, comment).then((data) => { if (data.error) { console.log(data.error) } else { this.props.updateComments(data.comments) } }) }
