lua how to make a loop

1-- For K,V in table
2for k,v in pairs(tbl) do
3 print(k)
4 print(v)
5end
6-- For i=0, num
7for i=0, num do
8 print(i)  
9end

1for init,max/min value, increment
2do
3   statement(s)
4end

1for startValue, EndValue, [increments] do
2        --code to execute
3end
4--The increments value is optional.  If it isn't defined, it is assumed to be "1"

1-- for in/for loops
2for key, value in pairs(table) do
3	-- If value is a table then you can do another iteration tho, for in for in isn't recommended.
4end
5
6for key, value in next, table do
7	-- Same as above.
8end
9
10for variable = 0, 1, 1 do
11	-- The variable is automatically set to the first value you input after "=".
12	-- The variable is then incremented by the third value you input after "="
13    -- until it reaches the second value you input after "=".
14
15	variable = variable + 1 -- The above only works if you increment it,
16	-- else it infinitely loops through the block.
17end
18
19while true do
20	-- Infinite loop
21end

1while expression do
2  --code
3end
