How would I reverse a table?

#1

Like let’s say I have a table that’s

{“I”, “like”, “tables”}

How would I change that to

{“tables”, “like”, “I”}

?

I’ve been messing around with the table.sort() function and maybe it’s because I’m blind or dumb but I can’t get the result I want. Help?

for i = 1, math.floor(#t/2) do
   local j = #t - i + 1
    t[i], t[j] = t[j], t[i]
end

Thank you so much!

Can you explain how that works? Because there’s no way I would have figured that out.

It loops up to half of the table and for each position in the first half, swaps it with the corresponding position in the second half.

If t is a table with five elements, it would loop over i = 1, 2, meaning it will swap t[1] with t[5] and t[2] with t[4] and that’s all you have to do. (t[3] doesn’t change since it’s the middle value here) Also works with evenly sized arrays.
