What are the best practices for using the Node.js File System module?

When using the Node.js File System module, it's important to follow best practices like using asynchronous methods, handling errors properly, and ensuring file paths are correct.

Can you explain why asynchronous methods are preferred?

Asynchronous methods prevent blocking the event loop, allowing your application to handle other requests while waiting for file operations to complete.

What are some common errors I should handle?

Common errors include file not found, permission denied, and invalid file paths. Always use try-catch blocks or error callbacks.

How can I ensure file paths are correct?

Use the path module to resolve paths and avoid issues with relative paths. Always validate user input for file paths.

Any tips for reading large files efficiently?

Consider using streams to read large files in chunks, which helps manage memory usage and improves performance.
