How to optimize if statements - can't remember term

I'm pretty sure there's a better way to write multiple condition if statements and thier result - but I can't remember the term/method so I can't find the scripting reference.

I want to optimize something that looks like this for example:

  if(playerLocation == there){
     
     moustache = long;
     
     }
     
     if(playerLocation == here){
     
     moustache = short;
     
     }
     
     if(playerLocation == inATree){
     
     
     moustache = GODLY;
     
     }
     
     if(playerLocation == inAHouse){
     
     moustache = whatMoustache;
     
     
     }

If anyone can point me in the right direction that would be moustache appreciated. I'm trying to optimize my code now :)
