Real-time commenting system

Things I struggled with that I am still working on:

• when I initially built this, I used pure JavaScript. However, it proved challenging when I tried to add the functionality for the replies associated with individual comments. I am still learning frameworks so I can modify and improve that functionality but any suggestions regarding building it the old fashioned way are more than welcome.

Things I added that weren't expected of me:

• I created some modals - one that pops up when you've already upvoted a comment/reply and one that pops up when you've already downvoted them.
• Also added a hide reply button in case one would want to censor it for sensitive visitors. However, I intend to fix that feature since it isn't perfect yet - it was kind of a test run to see if I could do it, and so I did!

Areas of my code I am uncertain of:

• how well my reply elements were constructed;
• perfect coordination for responsiveness;
• how to assimilate it into a full stack application (SPA)
