Can't parse json with node.js

I am a node.js beginner and I am trying to read a json file, but when I\'m running \'npm start\' in the terminal I get this error:

SyntaxError: U

readFile is the asynchronous version. You should either just use readFileSync, or rewrite it to be properly asynchronous.

console.log('analoc request');

var fs = require('fs');

 fs.readFile('./files/sample_data.json', function(err,config){
console.log('Config: ' + JSON.parse(config));
});

Or:

var config = fs.readFileSync('./files/sample_data.json');
console.log('Config: ' + JSON.parse(config));
