-## Built-in modules
-
-Node has numerous built-in methods that provide helpful utility methods:
-
-* [File system module](File%20system%20module.md)
-* [Events module](Events%20module.md)
-
-## Structure of Node module methods
-
-Every method belonging to the in-built modules of Node has a callback structure: a callback function of which the first argument is an error-handler and the second is the (typically asynchronous) returned value. 
-
-For example 
-
-````js
-
-fs.readdir('./', function(err, files) {
-	if (err) {
-		console.error(err)
-	} else {
-		console.log(files)	
-	}
-})
-
-// ['files', 'that', 'were', 'returned']
