How often is the move function called to update the snake's position?

The move function is typically called every 40 milliseconds to update the snake's position in games that follow a specific frame rate or update interval. This timing helps create smooth motion and controls for the snake, allowing the game to run efficiently while providing a responsive experience for the player.

Choosing 40 milliseconds as the interval allows for a good balance between performance and responsiveness. If the interval is too long, the game's responsiveness could suffer, making it feel sluggish. Conversely, an interval that is too short may result in unnecessary processing load without significant benefits to the gameplay experience. Thus, the 40 milliseconds interval is ideal for creating gameplay that feels smooth and engaging.

The other timings, like 20, 30, and 50 milliseconds, either create too rapid an update or too slow a response, which would affect overall gameplay consistency and enjoyment.
