This approach follows modern JavaScript best practices and improves code readability.\r\n\r\n#### Proposed Changes:\r\n- Replace the `switch` statement with a `keyToDirection` object that maps key codes to movement directions.\r\n- Use the `??` (nullish coalescing) operator to handle invalid key presses more cleanly.\r\n- Ensure `const` and `let` are used for block-scoped variables to improve scoping and maintainability.\r\n\r\n#### Benefits:\r\n- Simplifies the key handling logic, making it easier to read and maintain.\r\n- Enhances flexibility for future key mappings or modifications.\r\n- Adheres to modern JavaScript standards, leading to better performance and clarity.\r\n\r\nHere is an example of the proposed refactor:\r\n\r\n```javascript\r\nconst keyToDirection = {\r\n    37: 3, // Left arrow\r\n    65: 3, // 'A' key\r\n    38: 0, // Up arrow\r\n    87: 0, // 'W' key\r\n    39: 1, // Right arrow\r\n    68: 1, // 'D' key\r\n    40: 2, // Down arrow\r\n    83: 2  // 'S' key\r\n};\r\n\r\nconst directionFound = keyToDirection[keyNum] ?? -1;\r\n","author":{"url":"https://github.com/dmcote-1991","@type":"Person","name":"dmcote-1991"},"datePublished":"2024-09-25T02:04:25.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/118/JavaScript-Snake/issues/118"}
