Simple Table question

#1

If I want to reuse a table variable which is the correct way or does it matter??

local t = { {1,2,3,4}, {1,2,3,4}, {1,2,3,4} } --do things-- --re-init the table-- t = nil t = {}

or is this fine?

local t = { {1,2,3,4}, {1,2,3,4}, {1,2,3,4} } --do things-- --re-init the table-- t = {}

Best way would be to actually clean the table and reuse it entirely (creates less garbage on the long run).
But writing t = nil first or not, shouldn’t make any difference as long as the variable doesn’t reference that table anymore.
