If you look at the 2014 State of ClojureScript survey, these are the top items for What has been most frustrating for you in your use of CLJS?, and my take on work done in these areas is below. It is nothing short of amazing, IMHO.

Therefore I urge you to do the current survey.

1. Difficulty using ClojureScript REPL: The Node.js REPL was added, as well as a Nashorn REPL, as well as a lot of new "ease-of-use" stuff baked into all base REPLs (doc, pst, etc.). Additionally, a few new ClojureScript REPLs (Ambly, Replete, Planck) rely heavily on new stuff in ClojureScript.
2. Difficulty debugging generated JavaScript: Source map capability was essentially extended to all REPLs with stack traces automatically being mapped. The

Thank you for extending an invitation to speak at HighLoad++. I
sincerely appreciate your consideration.

I am an outspoken advocate for LGBTQ equality; this position is deeply
woven into my work. Clojure From The Ground Up is adamantly
LGBT-inclusive. Jepsen is named after a gay pop anthem and includes
dozens of references to same-sex relationships and trans identities. My
talk slides are populated with bearded nuns, genderqueer punks, and
trans hackers. My twitter feed is about as gay as it is possible to get.

What is the appeal of dynamically-typed languages?

Kris Nuttycombe asks:

I genuinely wish I understood the appeal of unityped languages better. Can someone who really knows both well-typed and unityped explain?

I think the terms well-typed and unityped are a bit of question-begging here (you might as well say good-typed versus bad-typed), so instead I will say statically-typed and dynamically-typed.

I'm going to approach this article using Scala to stand-in for static typing and Python for dynamic typing. I feel like I am credibly proficient both languages: I don't currently write a lot of Python, but I still have affection for the language, and have probably written hundreds of thousands of lines of Python code over the years.
