 # Parallel File Processing
 
+Class 3 of 401
+
+### reader()
+`reader()` is used to read the content of multiple files. 
+reader takes in two parameters, an array of paths, and a callback function e.g. `reader(path,callback)` 
+
+```
+reader(['foo.txt', 'bar.txt, 'wic.txt'], (err, data) => {
+  if (err) return console.error(err);
+  console.log(data);
+});
+
+>> foo
