fsunlinkSync

fsunlinkSync is a synchronous function provided by the Node.js fs (file system) module. It is used to delete a file from the file system. The function takes a single argument, which is the path to the file that needs to be deleted. If the file is successfully deleted, the function returns undefined. If an error occurs during the deletion process, the function throws an error.

The fsunlinkSync function is a blocking operation, meaning that it will pause the execution of the program until the file has been deleted or an error has been thrown. This can be useful in situations where it is important to ensure that a file has been deleted before continuing with the rest of the program.

It is important to note that fsunlinkSync should be used with caution, as it permanently deletes a file from the file system. If the file is needed for future use, it should be backed up before calling fsunlinkSync. Additionally, if the file does not exist, fsunlinkSync will throw an error, so it is important to check for the existence of the file before attempting to delete it.

In summary, fsunlinkSync is a synchronous function provided by the Node.js fs module that is used to delete a file from the file system. It is a blocking operation that takes a single argument, the path to the file to be deleted, and returns undefined if successful or throws an error if unsuccessful. It should be used with caution, as it permanently deletes a file from the file system.
