Dart is an open source class based, object oriented, optionally typed programming language that allows us to develop browser based one page web applications.
We can execute the code that should run on the client side either by using a web browser that supports Dart or by compiling our code into JavaScript. Using the Dart virtual machine we can execute code written in Dart on the server side.
void main() { print("Hello, World!"); }
The following video clip overviews this code sample, shows its execution and explains it.
