Yes, when Dart was still recently released I fully expected at least Chrome of all browsers to directly support it, and with it being an open source project, it to perhaps even trickle out to other browsers as well.<p>And I saw a Dart-powered web, and it was beautiful. Calling it a Javascript killer is a misnomer, because it&#x27;s a Javascript eviscerator.<p>Now Typescript is here in full force and I honestly think that, assuming the language isn&#x27;t going to be browser supported, that this is a better idea. :&#x2F; Simply because TS is a superscript over JS, so developers can migrate their projects over time. Regardless how much of it is still in JS, that is per definition also TS.<p>I think that is a huge boon, along with Typescript definition files to TS:ify libraries without having to restort to what the Dart guys seem to have been forced into doing with full reimplementations (DQuery, Bootjack, ... rather than simply downloading the appropriate files from DefinitelyTyped.org).<p>It&#x27;s too bad, because _conceptually_ I like Dart more! Everything is so coherent regardless if it&#x27;s on the client or the server, and modern HTML5 features are suddenly just libraries in the language itself! I really like it, I don&#x27;t even have to &quot;want&quot; to like it, I already do. Kind of annoying. :P
