Using jjs in Interactive Mode
If you run jjs without specifying any options or script files, it is run in interactive mode.
The script is interpreted as you enter it. Recall that strings in Nashorn can be enclosed in
single quotes or double quotes.
The following are some examples of using the jjs tool in interactive mode. It is assumed
that you have included the path to the jjs tool in the PATH environment variable on your
machine. If you have not done so, you can replace jjs with JDK_HOME\bin\jjs in the
following command. Remember to execute the quit() or exit() function to exit the jjs tool:

c:\>jjs
jjs> "Hello Nashorn"
Hello Nashorn
jjs> "Hello".toLowerCase();
hello
jjs> var list = [1, 2, 3, 4, 5]
jjs> var sum = 0;
jjs> for each (x in list) { sum = sum + x};
15
jjs> quit()
