Iterating through an array?
I'm attempting to iterate through an array, like the following:
1 | local array ={ |
2 | ['hi'] = "Hello"; |
3 | ['test'] = "Greetings"; |
4 | } |
and print out the key and value like:
hi = Hello
My current code is:
1 | for i,v in ipairs(array) do |
2 | print(i.." = "..v) |
3 | end |

ipairs specifically only iterates through integer numerical indices. What you want to use is pairs:
1 | for i,v in pairs(array)do |
2 | print(i.." = "..v) |
3 | end |

I agree with Undeniable, though unfortunately, I do not have enough reputation to up-vote. Just know that if I could, I most certainly would. antonio6643 426 — 9y

It's worth pointing out that 'i' for 'index' isn't a good variable name in this situation, because you're not using a list. Perci1 4988 — 9y

Index doesn't necessarily mean integer. An index can be anything. It could be the table itself. t={} t[t]=t print(t==t[t[t[t]][t]]) 1waffle1 2908 — 9y

well, what I see happening is you are putting tables in arrays and the tables are something, idk your thing is hard to read. What I would do though is.
1 | local array = { |
2 | Hi = "Hello", -- hi is just a codename for Hello like print(array.Hi) would print out Hello |
3 | Bye = "Good-Bye" |
4 | } |
5 |
6 | for i,v in pairs(array) do |
7 | print(v) |
8 | end |
