*SOLVED* A really-really small question.

Hi.

Um, can't find answer anywhere else..
What does number sign (#) operator do in Lua?

[Doctory]

gives you the size of a table.
for ex, a table has 3 items, table[1], table[2], and table[3]
if you use #table, it will return 3, because thats how much items the table has

Huge thanks!

[Doctory]

no problem

Note that it only works for the numeric part of a table (starting from 1, going until the next index is nil), so if you have gaps, then it won't report the "true" size of the table... and it doesn't count any other key either.

Let's not forget strings.
str = 'This is a string'
#str returns length of str - 16.
