Couldn't really get started (with the latest clean install of leiningen from homebrew).

  $ lein cljsbuild auto async-tutl
  ...
  java.lang.Exception: Unknown build identifier: async-tutl

Did the name of the tutorial change?

edit: ell instead of 1. I guess that's why I use a heavily-serifed font for my coding. I even re-read the command several times looking for a simple typo to catch exactly this problem.

You have a typo there. The proper command is:

$ lein cljsbuild auto async-tut1

Note the one instead of the ell.

The project is async-tut1 not async-tutl. Look at your project.clj.

Being totally new to Sublime I was actually got confused on configuring paredit and lispindent with Sublime 2.

    get sublime2 http://www.sublimetext.com/2
    package control https://sublime.wbond.net/installation#st2


	launch "sublime 2"
	ctrl-`
	paste in the package control script (from above link) <ret>
	re-launch "sublime 2"

	⌘-shift-p # dialog comes up
	install ↓ <ret>
	# up will pop a dialog after reading the package database
	paredit <ret>
	⌘-shift-p
	install ↓ <ret>
	lispindent <ret>

The extra level of detail would cloudy the main flow of the tutorial so maybe have some supporting material links for the slower kids?

This is great. We currently hold a weekly clojure class at work, and this will be very helpful to some of the people who attend. The more content the better!

Suggestion: add a form around the input and button, and bind on its submit. That makes the application work when pressing [return] from the input field

(you'll have to include a (.preventDefault e) in the (listen) callback though)

The (.log js/console (dom/getElement "query")) command returns "null" instead of a DOM element. Curiously, manually running the equivalent command in the Chrome console works as expected:

  > goog.dom.getElement
    function (element) {
      return goog.isString(element) ?
        document.getElementById(element) : element;
    }
  > goog.dom.getElement("query")
    <input id=​"query" type=​"text">​

If someone could provide a good pointer to better understand lisp syntax / Clojure I would appreciate it. Clojure is so confusing and hard to follow for the beginner!

The biggest difference is that functions go after the left-paren, not before. Commas are also unnecessary, they're just whitespace

    foo(bar, baz) => (foo bar baz)

    herp(bar, derp(baz)) => (herp bar (derp baz))

This might help as well: http://adambard.com/blog/clojure-in-15-minutes/

Perhaps note that scripts should be loaded after form elements. You get an odd error if (init) runs before the form elements exist.

I love this example. Working through this made me finally get started on reading Hoare's CSP book. Thanks!

Love CLJS!.
