File System is an essential built-in module of Node that contains utility methods for working with files and directories.
|
||
|
|
|
||
|
|
Every method associated with `fs` has a *blocking* and *asynchronous* implementation. The former obviously blocks the [event queue](Event%20queue.md), the latter does not.
|
||
|
|
|
||
|
|
The asynchronous methods are useful to have in some contexts but in general and with real-world applications, you should be using the async implementation.
