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

case, javascript, switch-statement

Solution

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.

Problem

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 !
