if,if,if, string cases, and if not, then something else?

I’ve added chat emotes, and commands to my chat, but how do I check for several cases of inputs, and if none of them just do a normal one. e.g.

If /dance
Then…

If /Smile
Then…

And in the end, if nothing of the ones above, then do normal text. How do I do this context of many if cases, or could I use a wild card, to check if first character of the string is a “/” … Cutout from the code (.js):

if(inputField == "/smile")
{
inputField = "ARRRRRRRRRRRRRRRGH SMILE!";
}
 
else
{ 
// Normal chat output would go here. 
}

Use a Switch-Case :

 private var inputField : String = "/smile";

 switch(inputField )
 {
     case "/smile" :
         // do stuff for condition 1
         outputField = "ARRRRRRRRRRRRRRRGH SMILE!";
     break;

     case "/frown" :
         // do stuff for condition 2
         outputField = "why so down?";
     break;

     case "/angry" :
         // do stuff for condition 3
         outputField = "Look Out";
     break;

     default :
         // do stuff if none of the above
         outputField = "Nice Day !";
     break;
 }
