While true, you should iterate integer-key tables using ipairs and hash tables using pairs.

Continue doesn't exist? I swear I've used it in Lua 5.1.
- seany 14y agoipairs is gone in 5.2
- Dylan16807 14y agoThey changed ipairs around a couple times. It's currently in. Either way you should be using not-pairs. If you construct a table in a weird way you can end up with pairs going out-of-order. ipairs works fine, also "for i=1,#t" works fine.
- vor_ 14y agoThere's no continue. Instead, you must use goto. > While true, you should iterate integer-key tables using ipairs and hash tables using pairs. In my opinion, this makes Lua's combination of arrays and dictionaries pointless since one must distinguish between them anyway for iteration.
- Hinrik 14y agoDo you really consider that to be a drawback? How often do you find yourself wanting to iterate a datastructure without knowing whether it's an array or a hash?
