table.maxn
Example
Demonstrates how this differs from the # operator.
local tbl = {"One", "Two", [6] = "Six", [42] = "Answer to life, the universe, and everything"}
PrintTable(tbl)
print("\n" .. #tbl)
print(table.maxn(tbl))
Output:
1 = One
2 = Two
6 = Six
42 = Answer to life, the universe, and everything
2
42
Whereas the length operator (#) returns the highest sequential
index, this returns the value of the highest numeric
index.
