I doubt there's a noticeable difference between a switch and a

In AS 3.0 bytecode, though, switches and equivalent conditionals
are not
necessarily compiled into the same bytecode. In fact, there's a
lookupswitch
instruction (opcode 0x1b). Of course, any switch can be implemented
as a
series of if / else if statements, but that's up to the compiler.
From my
(limited) experience, the Flash IDE always uses a switch bytecode
whenever
it finds a switch construct in Actionscript code. I don't know how it
affects runtime performance, but my guess is that it doesn't have much
impact. And, thinking about it, maybe that opcode exists because
it's an
optimized way to compile / execute a series of related conditions.

Switch/case is a bit quicker.

Hi guys
quick question that came up in a conversation I had the other day
- are
switch statements more or less efficient than a series of if...else
statements in either AS2 or AS3?
I'd always thought that the most efficient was the switch
