A Hello World application gives a computer programmer confidence that his development system is working properly. It is typically a very small program which produces recognizable output.
In Java it is:
class HelloWorld {
public static void main (String args[]) {
System.out.println("Hello World!");
}
}
In JavaScript it is:
document.write('Hello World!');
