How does the in pairs function work? [closed]

Asked by

This question already has an answer here:

Can somebody explain to me what "In pairs", does and how to use it?

I never really understood the in pairs function, and as I get deeper into Lua, I feel like it is really useful, but I just can't understand it, can anyone help me?

It loops through the values of a table. User#11440 120 — 8y

How in pairs works is that unlike a normal for loop which iterates a certain amount, it iterates through a table/array.

So let's say I have an array with five values, I would call on it like so:

local mytable = {54, 3, 9, 10}

for i, v in pairs(mytable) do
    print(v)
end

The loop would print all of the values. Generic for loops like the one above are useful for iterating through an object's children effectively.

If this helped you, don't forget to accept the answer :)
