Difference between pairs and ipairs

The i in ipairs stands for integer. It’s the difference between iterating over an array and a dictionary. ipairs iterates over an array in order.

Difference between pairs() and ipairs()

Dictionaries can use integer keys, but ipairs will stop once there is a gap. local dict = { [1] = "Lemon", [2] = "Yellow", [3] = true, [5] = "ipairs won't see this one or any after it" } Using pairs on an array should still iterate over all the items (although potentially not in the order you expect). Using ipairs on a dict should probably be avoided. Arrays can be stored more efficiently than dictionaries and can be faster in some languages (depending on implementation). I don…

Is there a difference between in pairs and ipairs?

there is no difference except the fact that ipairs stops the loop when there is a nil value, lemme show you an example local Table = {"hi","Hello","welcome",nil} for _,v in pairs(Table) do print(v) end Output: hi hello welcome nil and than the ipairs local Table = {"hi","Hello","welcome",nil} for _,v in ipairs(Table) do print(v) end output: hi hello welcome it just stops and doesn’t continue when it hits a nil value

What is the difference between ipairs and pairs in for loops?

You shouldn’t use them interchangeably, as they have different behaviour when you really try them. The difference is, with ipairs, you only traverse the array part of a table, and if nil is encountered, ipairs, or I should say the function it returns, stops in its tracks. Here is an example: t = {9.734, 8, nil, "nice"} for _, v in ipairs(t) do print(v) end Output 9.734 8 If you want to guarantee order, use ipairs/numeric for loop. This link explains a way ipairs can be written and…

Ipairs or Pairs

ipairs is best but it needs to be an array without gaps. pairs must be used for dictionaries or arrays with gaps. The only “error” you could have with pairs is that the order is not guaranteed. With ipairs it goes through the array in order, hence needing to be an array with no gaps.
