Goals: Add links that are reasonable and good explanations of how stuff works. No hype and no vendor content if possible. Practical first-hand accounts of models in prod eagerly sought.
A list of commonly asked questions, design decisions, reasons why Clojure is the way it is as they were answered directly by Rich (even when from many years ago, those answers are pretty much valid today!). Feel free to point friends and colleagues here next time they ask (again). Answers are pasted verbatim (I've made small adjustments for readibility, but never changed a sentence) from mailing lists, articles, chats.
How to use:
- The link in the table of content jumps at the copy of the answer on this page.
- The link on the answer itself points back at the original post.

I am moving this gist to a github repo so more people can contribute to it. Also, it makes it easier for me to version control.
Please go to - https://github.com/praveenpuglia/shadow-dom-in-depth for latest version of this document. Also, if you find the document useful, please shower your love, go ⭐️ it. :)
Heads Up! It's all about the V1 Spec.
In a nutshell, Shadow DOM enables local scoping for HTML & CSS.

Since the recent release of Catalina, macOS has shipped with the ability to allow iOS/iPAD apps to run on macOS without any modification via a featureset known as Project Catalyst.
This is exciting, as writing React Native + Clojurescript apps as a target for the desktop is much more compelling than a pure Electron app (imo).

This describes how I setup Atom for an ideal Clojure development workflow. This fixes indentation on newlines, handles parentheses, etc. The keybinding settings for enter (in keymap.cson) are important to get proper newlines with indentation at the right level. There are other helpers in init.coffee and keymap.cson that are useful for cutting, copying, pasting, deleting, and indenting Lisp expressions.
The Atom documentation is excellent. It's highly worth reading the flight manual.
