Infinite loop

This is a common programming pattern using a while loop to create loops that run infinitely until an external condition is met.

This is done by setting the condition to (true) - this is always true, so the loop continues to execute indefinitely.

while (true) do 
-- code executes infinitley
end

This is often used in conjunction with if statements to loop until a specific condition is checked within the loop and exited if false.

For example, the following function will loop infinitely until counter == 5.

function countNumbers()
   local counter = 1
   while (true) do
      counter = counter + 1
      trace(counter)
      if counter == 5 then
         return counter  -- Exit the function and return the value
      end
   end
end
