Inquiry about equality operator

Hello all,
I couldn’t find a solid answer online about this.
When using the equality operator (==) on two tables, does it compare their contents or their memory address?
Thank you.

From the Lua handbook:

Lua compares tables, userdata, and functions by reference, that is, two such values are considered equal only if they are the very same object. For instance, after the code

a = {}; a.x = 1; a.y = 0
b = {}; b.x = 1; b.y = 0
c = a

you have that a==c but a~=b.

Tables are compared by memory address, content or the way it is stored (Arrays, Dictionaries) play no role in comparison.
