Interactive Comments Section Using Vanilla Js + Localstorage + JSON

Hello everyone this is my solution for this challenge it took me really long time (exactly one month) to finish. Why is it that hard? Well no and yes, im still new with JavaScript and its my first programming language but what made this project difficult is because its my first time dealing with a CRUD project and JSON file and localStorage all of these for the first time in one project was hard. but is it hard now? well its not after i understand how crud and localStorage works. this could be much easier using React even tho im going to study it very soon i still wanted to do this project with Vanilla JS to understand whats going on behind the scenes. Anyways Hope you like it, even tho there is still some little things i will fix such as submit a comment if the user click "Enter" and when you try to update the comment autofocus() go all the way to the start of the comment instead of the end
