请问HN：Dart是一种特别优化的前端开发语言吗？
你好。我记得当Dart被引入时，它被称为一种“JavaScript替代品”（？）用于浏览器。然而，它似乎“演变”成几乎仅在Flutter中使用，用于开发移动、网页和桌面前端。对我来说，这种语言如此专门用于前端的情况显得有些奇怪。即使是Ruby，在Rails之外也有一些边缘用例。Dart是否有任何特别的特性，能够证明将Flutter与之绑定的决定是合理的？还是这一切都是偶然的？谢谢。

Hi. I remember when Dart was introduced, it was supposed to be a "JavaScript alternative" (?) for browsers.<p>It however "evolved" into being almost only used in Flutter, for developing mobile, web, and desktop front-end development.<p>It seems bizarre to me that a language is so special-purpose for front-end. Even Ruby has some fringe use cases beyond Rails.<p>Does Dart have any particular features that justify such a decision to bind Flutter to it? Or it has all been accidental?<p>Thanks
