How does fs-extra.appendFile work?

fs-extra.appendFile is a method in the fs-extra library that allows a user to append data to a file.

When this function is called, it opens the file, appends the data to the end of it, and then closes the file. If the file doesn't exist, it is created. The function accepts three arguments: the file path, the data to append, and an optional encoding.
