This is the default title set by WordPress. Why “Hello World”, you ask?  Every programmer’s first assignment is to write a “Hello World” program. It is the easiest and uses the most basic function in any given language: the print statement. It’s a way of saying, “Hi!”

In Ruby, it is puts "Hello World!";
In PHP, it is echo "Hello World!";
In VisualBasic, it is Console.WriteLine ("hello world!")
In SQL, I suppose it may be SELECT "Hello World!" from TABLE
In Javascript, it is document.write("<b>hello world!</b>");
In ColdFusion, it is <cfoutput>Hello World!</cfoutput>
In Perl, it is print "Hello World. n";
In Java, it is System.out.println ("hello world!");
In C, it is printf ("hello world! n");
In Pascal, it is writeln("Hello World!");
In Turing, it is put "Hello World"

(A long while back, I used to write code for work.  This is in order of the latest language learned to the earliest language learned. Regrettably, I do not remember most of the syntax of any of these languages though I have a fondness for Pascal and can still do some JS.  I learned Ruby for an interview last summer and funny enough, I actually passed the tech interview and landed the job for a Ruby developer/tech lead role.  But I didn’t take it — I don’t see myself programming fulltime anymore. I leave that to the passionate hackers and experts out there.)
