The keyword break exits out of loop structures and switch statement.

When a label is used, JavaScript completely breaks out of the area designated by label.

To label a statement, place the label name followed by a colon (:).

Labels are useful when working with nested loops.

      {
        document.write("Counter1=",counter1);
        document.write(" Counter2=",counter2,"<BR>");
        if (counter2 == 3)
          break;
