Switch Case To/Between

Question

Is there a way in Javascript to compare one integer with another through switch case structures without using if statements?

E.g.

switch(integer) {

There is a way, yes. I'm pretty sure I'd use an if/else structure in my own code, but if you're keen to use a switch the following will work:

switch(true) {
   case integer >= 1 && integer <= 10:
      // 1-10
      break;
   case integer >= 11 && integer <= 20: 
      // 11-20
      break;
   case integer >= 21 && integer <= 30:
      // 21-30
      break;
}

Of course if you wanted to avoid having to code >= && <= on every case you could define your own isInRange(num,min,max) type function to return a boolean and then say:

switch (true) {
   case isInRange(integer,1,10):
      // 1-10
      break;
   // etc
}
