Don&#x27;t know what you&#x27;re referring to.  Dart&#x27;s release was well past by the time TypeScript debuted.[1]  Dart was announced in 2011.[2][3]  The only significance that 2013 has to Dart that I know of is that&#x27;s when Dart 1.0 was released.  If that&#x27;s what we&#x27;re measuring, TypeScript&#x27;s 1.0 coincided with Build 2014—still later than Dart&#x27;s corresponding date, and among other things, that would mean we could say Rust is less than a year old, even though it predates both.<p>1. <a href="https:&#x2F;&#x2F;channel9.msdn.com&#x2F;Shows&#x2F;Going+Deep&#x2F;Anders-Hejlsberg-and-Lars-Bak-TypeScript-JavaScript-and-Dart" rel="nofollow">https:&#x2F;&#x2F;channel9.msdn.com&#x2F;Shows&#x2F;Going+Deep&#x2F;Anders-Hejlsberg-...</a><p>2. <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=3092558" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=3092558</a><p>3. <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=M0lfNw8Tyhc" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=M0lfNw8Tyhc</a>
