Fastest and efficient way to loop through a list?

Hey guys,

I'm looking for alternative, faster and perhaps more efficient methods for looping through a list. Using a for loop seems like the more default method, but I'm sure there must be ways that are somewhat faster than that.


Thanks in advance, guys, have a nice day :P

for() is pretty much the best way, and the for(key in list) notion is actually the fastest way that exists in the language.

You could use for()'s other syntax like:

for(var/i = 1, i <= mylist.len, i++)
    world << mylist[i]


But it's not any faster, if anything it's slower because it does an index-lookup the way it does.

or, the the for-to-step format:

for(var/i = 1 to list.len) world << list[i]


with step, you can iterate over every other thing in the list, every 3, etc.
for(var/i = 1 to list.len step 2) world << list[i]


tho, the default x in container way is probs the best.
