I know how to use it for random numbers, but what about tables?
COMMUNITY QUESTION
How would you use math.random() for a table?
2 answers
If you have a table with numeric indices and want to get a random element from the table,
local t={"a","b","c","d","e","f","g"}
print(t[math.random(#t)])
writing math.random(#t) will produce a random number from 1 to the length of the table.
If what you mean is that you want to generate a table of random numbers, you can set the indices of a table to a random number:
local t={}
for i=1,10 do
t[i]=math.random()
end

Can you iterate what i = x means? I've never truly undestood it.

It's a numeric for loop. It iterates from 1 to 10 in this case, calling the code inside of it again for each value of i.
table[math.random(1,#table)]
-- would randomly choose something from a table

It would generate a random number between 1 and the number of elements in the table; it wouldn't cycle.

Can you clarify what you mean by using it for tables?
