Optimized performance for posting comments and notifications
Optimized it by:
* Making the functions run asynchronously in parallel (instead of synchronously one after another). Removed `async await` in the composite function postCommentAndNotif()
* Passing `this.content` as a param into all 3 nested functions within postCommentAndNotif(), before updating `this.content = ' '` to clear text input in comment textarea. Because "When you pass it as a parameter to the function it basically creates a copy of it. So if you change this.content the function will still have their own contentData variable" - kudos to @keenencharles for this! 🍻
