Dart is an open-source programming language created by Google that compiles to JavaScript and allows developers to build web and server applications with a single language. Dart is easy to learn and comes with features like classes, interfaces, optional static types, lexical scoping, libraries, and isolates. It also includes a lightweight editor. A basic Dart program defines a printNumber function that prints a number, declares and initializes a variable, and calls the function to print the number. Dart code execution is supported in the browser via JavaScript compilation and on the server. The Dart team includes Lars Bak and Gilad Bracha who have experience with Java, JavaScript, and software patents.

5. A Basic Dart Program
// Define a function.
printNumber(num aNumber)
{
print('The number is $aNumber.'); // Print to the console.
}
// This is where the app starts executing.
main()
{
var number = 42; // Declare and initialize a variable.
printNumber(number); // Call a function.
}
