Well there are other non-giant tech company based javascript frameworks those are just the two most likely to get you employed.

Well AngularJS was kind of dominating market share then Google dipped their fingers in it and its jumped 3 version numbers in a year sooooo ReactJS(made by Facebook by the way) is starting to be seen as more stable/professional. AngularJS is still more popular I'd say.

I wouldn't say it is completely irrelevant now but the industry as a whole is moving to front end frameworks like ReactJS or AngularJS which don't really require JQuery as they have their own implementations of most of the things JQuery does.

• Nested replies get ugly fast, as it would all cascade linearly.
• Can't upvoat/downvoat comments.
• Max comment size on a chain of comments would be stricter since its all in one field.
• Slightly more complicated validation to ensure users are only adding to the end of a comment not editing anything.

• Less server load to build the comment trees.
• Less DB space used
• Less API calls on voting up/down comments
