So, on one hand, yes. As a clojurian, I feel as if I should add an additional level of condemnation (the whole syntax of my favorite language is good old-fashion data structures, as is almost every construct within the language).

That being said, it's frontend stuff. The turnaround times are so small that those kinds of bugs are pretty hard to ignore, and very easy to find.

Note: I have used Angular, but don't use it anymore, for other reasons.
