Choose a random item from a table

Question

My goal is to pick out a random item from a table in Lua.

This is what I\'ve got so far, but it currently does not work:

local myTable = { \'a\', \'b\',          


        

Answer 1

I personally use the following function inspired by @ahmadh

function random_elem(tb)
    local keys = {}
    for k in pairs(tb) do table.insert(keys, k) end
    return tb[keys[math.random(#keys)]]
end
