There are differences between SWITCH and IF-ELSE-IF statements in other
languages, but in regards to Revolution someone from the engine team
would be best to answer it.
In many languages SWITCH statements are converted into a hash table for
much quicker lookups and using a SWITCH once or twice is slower than
using an IF-ELSE-IF statement due to the SWITCH statement getting
hashed, but using the same SWITCH statement multiple times will
increase the speeds.
Also, because of the fact that an IF-ELSE-IF statement is _always_
evaluated, they can never be faster than a SWITCH statement (they can
be just as fast, but never faster)
There are a few other differences between SWITCH and IF-ELSE-IF
statements that do not seem to apply to Revolution due to the fact you
can use SWITCH statements just like an IF-ELSE-IF statement. Example;
switch
case (tLUET < 42)
# do something
break
case (tLUET > 42)
# do something
break
case (tLUET = 42)
# do something
break
default
# do something
break
end switch
The above would usually need to be done with a IF-ELSE-IF statement
but, as you can see, Revolution can do it as a SWITCH statement.
