Do not use return, break, exit or continue
Return, break, exit, continue and throw are implemented using C++ exception.
C++ exceptions are SLOW!
TEST CASES:
|
fn test1a v = (if v == true do return 1; 0)
fn test1b v = (if v == true then 1 else 0)
|
FOR 100,000 ITERATIONS:
|
test1a true -- 15890 msec.
test1a false -- 78 msec.
test1b true -- 47 msec.
test1b false -- 62 msec.
|
TEST CASES:
|
fn test2a =
(
local res
for i = 1 to 1000 do
if i == 10 do (res = i; break;)
res
)
fn test2b =
(
local notfound = true, res
for i = 1 to 1000 while notfound do
if i == 10 do (res = i; notfound = false;)
res
)
|
FOR 100,000 ITERATIONS:
|
test2a() -- 84265 msec.
test2b() -- 1359 msec.

Previous Tip
matchPattern is faster than findString
Next Tip
Use StringStream to build large strings
