OVERVIEW
Dart is an object-oriented language with C-style syntax that can optionally transcompile into JavaScript. It supports a varied range of programming aids like interfaces, classes, collections, generics, and optional typing.
Dart can be extensively used to create single-page applications. Single-page applications apply only to websites and web applications. Single-page applications enable navigation between different screens of the website without loading a different webpage in the browser. A classic example is GMail ─ when you click on a message in your inbox, the browser stays on the same webpage, but JavaScript code hides the inbox and brings the message body on screen.
