Additional Notes
- pairs is faster than ipairs[1][2] - but returns values in an arbitrary order. Use ipairs if order is important , pairs otherwise.
- The down fall to ipairs is that it only works on tables with integer keys. Therefore, a table like this:
local tab = { "key1" = value, "key2" = value2, [10] = value3, generic_name = value4 }
Can not be iterated over by ipairs.
- for k,v in ipairs(tab) do is equivalent to for k = 1,#tab do local v = tab[k], but is neater. However, it is far slower.
- for k = 1, #tab do local v = tab[k] is faster than both ipairs and pairs
