--- Lua implementation of array.reduce() from Javascript.
|
||||||
|
-- @param tbl The table to iterate over.
|
||||||
|
-- @param func The function to call for every element in tbl. Will be passed the following arguments: accumulator, value, index, table. Of course, the provided function need not take this many arguments.
|
||||||
|
-- @param initial_value The initial value of the accumulator.
|
||||||

local function table_reduce(tbl, func, initial_value)
|
||||||
|
local acc = initial_value
|
||||||
|
for key, value in pairs(tbl) do
|
||||||
|
acc = func(acc, value, key, tbl)
|
||||||
|
end

return acc
