<pre>var fs = require('fs');

// blocking, synchronous way
var data = fs.readFileSync('/file.txt'); // blocks here until file is read
console.log(data); // do something with data

// non-blocking, asynchronous way
fs.readFile('/file.txt', function (err, data) { 
 if (err) throw err;
 console.log(data); // do something with data
});
</pre>

The fs.readFile() method is used to read files on your computer. 

There are two ways to use this method:

Synchronous: blocks code execution until the file has been read
Asynchronous: non-blocking; code continues to run while the file is being read

Synchronous example:
<pre>var fs = require('fs');

// blocking, synchronous way
var data = fs.readFileSync('/file.txt'); // blocks here until file is read
console.log(data); // do something with data
</pre>

Asynchronous example:
<pre>var fs = require('fs');

// non-blocking, asynchronous way
fs.readFile('/file.txt', function (err, data) { 
 if (err) throw err;
 console.log(data); // do something with data
});
</pre>
