You can do it like this:

dados = {
    nome = 'Wallace',
    idade = 25
}
for k, v in pairs(dados) do
    print(k, "=>", v)
end

I was seeing that there’s this one foreach, foreachi and foreachvar. That’s in old versions?

Note that they are functions and not commands. The command is for. The functions can be used, of course, they will receive Amble as parameters. The function semantics is a little different from the command, but it solves most situations well. In general I would avoid. This is almost the same as preferring jQuery to JS :)
