Dart

Dart is a programming language developed by Google that supports building apps targeting multiple platforms, including web browsers, WebAssembly, desktop and mobile apps. Its adoption has been driven by the dominance of Flutter — a popular, multi-platform UI toolkit powered by Dart — in the cross-platform native mobile app framework space. In response to community feedback, Dart has evolved since its initial versions and has added built-in sound null safety in version three, in addition to a robust type system. Furthermore, Dart's ecosystem is growing rapidly, with a vibrant community and a wide range of available libraries and tools, making it attractive for developers.

Dart is Google’s attempt at creating a programming language to replace JavaScript due to JavaScript’s perceived flaws and inherent performance issues. Dart, in line with previous Google languages, provides Java-like syntax and semantics that are intended to be more appealing than JavaScript’s prototype-based nature. Reception within the browser-development community has been understandably cool and it remains to be seen if the language will become more widely accepted, though Chrome’s continued rise and the search for alternatives like CoffeeScript may yet shift that balance.
