I have this JSON array, and what I want is to get the password field alone
var user = [ { _id: 5902086ecbc0dd11e4870fd9,
password: '$2a$08$FIpkmFT1WDZggQYyBA4CVuop6pelbKBfUEJ1/KAVIV2Si9Ho1EYhi',
email: 'jv100@gmail.com',
lastName: 'v',
firstName: 'j',
updatedDate: 2017-04-27T15:04:14.483Z,
createdDate: 2017-04-27T15:04:14.483Z } ]
I tried to parse it using this code
var obj = JSON.parse(user);
console.log(user.password);
but still it is undefined.
User is already a list of objects, so you don't need to parse it. However, it is an array. So if you meant for it to be an array, you'd need to access the password by using this code:
console.log(user[0].password);
It's already an array there is nothing to parse. You can access your property via :
console.log(user[0].password);
You can't access your property with user.password because user variable is not object, it's an array, your object is stored at the zero index of your array.
You already have JSON object. hence, no need to parse it again.

var password = user[0].password;
console.log(password);
