<a href="http:&#x2F;&#x2F;www.scala-js.org&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.scala-js.org&#x2F;</a> has a nice comparison between JavaScript, ECMAScript 6, TypeScript and Scala.<p>I&#x27;m not sure there is much substance to develop &quot;native&quot; programs in TypeScript&#x2F;Haxe&#x2F;... they don&#x27;t have an ecosystem outside the web, while Scala has tons of mature libraries, access to all the Java stuff ever written, and runs on the best, mature, well-supported, high-performance runtime you can get.
