  ==== Evolving Dart: Leaving the ocean and learn to fly by Leaf Petersen
  
  A Dart history: past, now, future. At the beginning, Dart was design to be a great JIT language to replace the "flawed" JavaScript in the browser. Then they adapted the language by creating Strong Mode. Then, came AOT with Flutter and the new version, Dart 2.
  
  To extends the language to Dart 2, main challenge was to make a static typing system, who is both developer-friendly and as easy to use as the dynamic typing of Dart 1. Core libraries and tools have been updated to work with Dart 2.
