You are tasked with creating a Go program that can read and write data to a file. How would you handle potential errors that might occur during file operations?

In Go, it's essential to handle potential errors that may occur during file operations gracefully. Using panic to stop program execution is not recommended for handling errors. Instead, you should check for errors using the if err != nil pattern and handle them by logging error messages and taking appropriate actions. Ignoring errors is also not advisable, as it can lead to unexpected program behavior. Creating a custom error-handling mechanism like an ErrorHandler class is not a standard practice in Go; it's better to use the built-in error handling mechanisms provided by the language.
