I have a table

{
['i']=0,
['o'] = 1
}

Can I get the index names rather than the index value?

You can save code:


function getIndex(tab, value)
  local indexes = {} 
  for index, var in pairs(tab) do
    if var == value then 
      table.insert(indexes, index) 
    end 
  end 

  return table.unpack(indexes)
end
