Google launched a website for developers: JavaScript vs. Dart
Google has taken another step to popularize the Dart language, which is positioned by the search giant as a replacement for JavaScript. The company launched the Dart Synonym promo site for developers, which makes it easier to compare the syntax of both languages, conveniently placing the code samples in two columns and generously putting JavaScript in the first place. The examples themselves cover a very wide range: it starts from variable declarations, covers topics such as working with arrays, strings, DOM manipulation, and ends with object-oriented programming, so that a site can, in principle, serve as a quick reference for both Dart and Javascript
