The final ELSE or an ELSE in a single IF statement will always be optional. It's there to allow you to have a block of code ran by default if none of your conditions are met. If you have an IF ... ELSE then the code block in your ELSE will run if the IF isn't met. Just-the-same, If you have 3 ELSEIFs (which by this point you should look into using a SWITCH statement), you can use a final ELSE to run some code if the initial IF and any of the ELSEIF's conditions weren't met. If you just want to test certain conditions and only want to run code if a certain condition is met, you can omit the final ELSE. Hope this helps.
Cheers!
