Can I use a case/switch statement with two variables?

Question

I am a newbie when it comes to JavaScript and it was my understanding that using one SWITCH/CASE statements is faster than a whole bunch of IF statements.

However, I want to use a SWITCH/CASE statement with two variables.

My web app has two sliders, each of which have five states. I want the behavior to be based on the states of these two variables. Obviously that is a whole heck of a lot of IF/THEN statements.

One way I thought about doing it was concatenating the two variables into one and then I could SWITCH/CASE that.

Is there a better way of accomplishing a SWITCH/CASE using two variables ?

Thanks !

Yes you can also do:

    switch (true) {       case (var1 === true && var2 === true) :        //do something        break;      case (var1 === false && var2 === false) :        //do something        break;        default:      } 

This will always execute the switch, pretty much just like if/else but looks cleaner. Just continue checking your variables in the case expressions.
