Completion Instructions

Functionality to be added

The app must have the following functionalities

• Initially, the list of comments should be zero and the inputs fields should be empty
• When non-empty values are provided and Add Comment button is clicked,
  • A new comment should be added to the list of comments
  • The comments count should be incremented by one
  • The value of the input fields for name and comment should be updated to their initial values
• When the Like button of a comment is clicked, if the image for Like is
  • Like image, then it should be changed to the Liked image
  • Liked image, then it should be changed to the Like image
• When the Delete button of a comment is clicked, the comment should be deleted from the list of comments and the comments count should be decremented by one

Components Structure

Use these files to complete the implementation:

• src/components/Comments/index.js
• src/components/Comments/index.css
• src/components/CommentItem/index.js
• src/components/CommentItem/index.css

Quick Tips

• The formatDistanceToNow function in the date-fns package is used to return the gap between the given date and now in words.

import {formatDistanceToNow} from 'date-fns'

console.log(formatDistanceToNow(new Date())) // less than a minute

Important Note

The following instructions are required for the tests to pass

• HTML input element for name should have the placeholder as Your Name
• HTML textarea element for comment should have the placeholder as Your Comment
• The Like image for each comment should have the alt as like

Things to Keep in Mind

• All components you implement should go in the src/components directory.
• Don't change the component folder names as those are the files being imported into the tests.
• Do not remove the pre-filled code
