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

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

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
