Nested switch statement in javascript

by

Your approach is absolutely fine.

You can make the switch nesting less complex by using switch (true):

switch (true) {
  case ((id1 === 1) && (id2 === 1) && (id3 === 1)) :
  case ((id1 === 1) && (id2 === 1) && (id3 === 2)) :
  case ((id1 === 1) && (id2 === 2) && (id3 === 1)) :
  case ((id1 === 1) && (id2 === 2) && (id3 === 2)) :
  case ((id1 === 2) && (id2 === 1) && (id3 === 1)) :
  case ((id1 === 2) && (id2 === 1) && (id3 === 2)) :
  case ((id1 === 2) && (id2 === 2) && (id3 === 1)) :
  case ((id1 === 2) && (id2 === 2) && (id3 === 2)) :
}
