How to count how many times an element appears in a table?
Say that I have a table like this:
local table = {"1", "1", "2", "3", "4"}
for i,v in pairs(table) do
print(v)
end
How would I go about creating a function that counts how many times each item is in the table? For example, it would return 2 for "1", but it would return 1 for the others. Thanks.

local table={"1","1","2","3","4"}
local table_count
for i,v in pairs(table) do
--adding the information from the original table to a count
if not table_count[i] then
table_count[i]=1
else
table_count[i]+=1
end
end
--function that will return how many times an object is in the original table.
local function count_returner(identifier)
if table_count[identifier] then
return table_count[identifier]
else
--[[will return false since there are no instances of the item you are looking for. you can also change this to 0 if you like]]
return false
end
end
the above code will work but it is probably a "dumb" way; there are probably more straightforward solutions.
