rock paper scissors with loop

jpengineer (6)
How can I easily display what the computer chose and what the user chose in words? i.e. rock paper or scissors. I am thinking an if-else statement but is there anyway to just assign the numbers to the strings inside that function?

Instead of if-else statements you can use a lookup table.
Maybe you want to have a look at my demo.
