What is the usage of " # " in scripting?

[DeVague_RBLX (Sheriff)]

I see many programmers use " # " in their scripts and I’m just wondering … What is it used for?

The # operator is used the get the length of a table.

What did I tell you lol! People help in these forums

[DeVague_RBLX (Sheriff)]

Do you even think I understood it smoothly lol. English is not my main language.

Edit: After thinking for minutes, I actually understood it, but Idk why is it important or how it is used.

you will realize how useful this is later.

local t = {}

for i,v in pairs(workspace:GetDescendants()) do
table.insert(t, v)
end

if # t > 10 then
print(# t)
end

It can also be used for getting the length of a string.

print(#"Hello!") -- 6
