I couldn&#x27;t help reading the emphasized &quot;types&quot; in &quot;optional types&quot; as a yell for the Typescript developers to come back.<p>But I too hope that Dart will become more successful, because let&#x27;s stop beating around the bush -- it isn&#x27;t now, not relatively speaking and comparing to the state of web development today. And this is unfortunatenly _not_ because web development hasn&#x27;t been rapidly evolving the past few years.<p>But enough negativity. I found this part the most interesting, because today there are already so many ways to get various non-officially sanctioned languages onto both iOS and Android:<p>&gt; Soon, you’ll be able to write Dart code for micro-processors (think Raspberry Pi) and — more interestingly — for micro-controllers (think Arduino). This means developing for really compact, really cheap, really low-energy devices is no longer a C&#x2F;C++&#x2F;asm club.<p>Maybe Dart can at least find an unexpected niche?
