JSON.parse can be used to parse JSON Content.
The below example shows how to parse JSON content by reading it from a file.

Sample File with JSON Data (sample.js)

{
   "capital":"chennai",
   "location":"south",
   "stadium":{
      "cricket":"chepauk",
      "football":"mooremart"
   }
}

Node JS Code (jsonparser.js)

var fs = require('fs');

var content = fs.readFileSync('./sample.js').toString();

var jsoncontent = JSON.parse(content);
console.log(jsoncontent);

//Reading particular value
console.log("\nCapital is:" +jsoncontent.capital);

Running the Code

$ node jsonparser.js

{ capital: 'chennai',
  location: 'south',
  stadium: { cricket: 'chepauk', football: 'mooremart' } }
