The main thing stopping me from using Dart is the same thing as Java and Python and others.  It isn&#x27;t designed to compile in the browser.  You have to use the command line or an IDE.  I have no problems with those myself, but the apps I am interested in involve letting end users create their own apps&#x2F;animations&#x2F;simulations, etc.  If they went forward with a Dart VM in the browser, that would be great, but it sounds like that was one of the first things they abandoned.<p>There are so many other languages that do compile in the browser and can be used without relying on command line tools that there&#x27;s no reason to pay any attention to dart at all, even though I like everything else about dart: <a href="https:&#x2F;&#x2F;github.com&#x2F;jashkenas&#x2F;coffeescript&#x2F;wiki&#x2F;List-of-languages-that-compile-to-JS" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;jashkenas&#x2F;coffeescript&#x2F;wiki&#x2F;List-of-langu...</a>
