  "main": "app.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "Tanmay Sarkar",
  "license": "ISC",
  "dependencies": {
    "body-parser": "^1.17.0",
    "express": "^4.15.0"

		lname : 'Sarkar'
	},
	{
		fname : 'Harold',
		lname : 'Finch'
	},
	{
		fname : 'John',
		lname : 'Reese'
	}
]
app.get('/',function(req,res){
	res.json(person);
	console.log('user accessing array parsing page');
});
app.listen(5000,function(){
	console.log('server running on port 5000');
})
