If there's something in the tutorial that trips anyone up or doesn't make sense please let me know and I will amend. I'm pretty excited about the latest release of ClojureScript that makes all this possible. With respect to speed of incremental compiles, code size, performance of generated code, and debugging we're finally in a good place (with of course many improvements planned in the near future). None of this would have been possible without the tireless work of 62 contributors over the past two years, http://github.com/clojure/clojurescript/ http://github.com/clojure/clojurescript/. A big thank you to all! Happy hacking!

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!

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.

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!

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?

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/ http://adambard.com/blog/clojure-in-15-minutes/

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">
