I have a collection and using the Lodash _.find method, I want to return the object with the title matching "Development".

So I have the following code which I had hoped would return what I wanted:

// Define rooms
var rooms = [
  { title: 'Just For Fun', created: '2016-10-23T16:57:03.288Z', id: 2 },
  { title: 'Development', created: '2016-10-23T16:57:03.294Z', id: 6 }
];
// Load lodash module
var _ = require('lodash');
// Expected object for development?
console.log(_.find(rooms, {'id': 6}));

However, what I get back in the console is simply undefined. The documentation has the following example:

var users = [
  { 'user': 'barney',  'age': 36, 'active': true },
  { 'user': 'fred',    'age': 40, 'active': false },
  { 'user': 'pebbles', 'age': 1,  'active': true }
];
// The `_.matches` iteratee shorthand.
_.find(users, { 'age': 1, 'active': true });
// => object for 'pebbles'

So they get pebbles but I get undefined? Can anyone indicate where I am going wrong here? Thanks in advance!

I am using Node.

• javascript
• node.js
• lodash

• (1) Can you show your code in one code block, so the order is clear? Have you defined room before doing the _.find? (2) how have you installed lodash? (3) which version of Node are you running on? – trincot Commented Oct 23, 2016 at 17:24
• @trincot I see what you're getting at but I was indeed defining rooms before the console.log(). Have updated my question. – Craig van Tonder Commented Oct 23, 2016 at 17:30
• 1 You know of course that console.log itself returns undefined so that will be output to the console. The line above that should be the element it found. Usually screen shots are a bad idea but in this case it might be useful. – user663031 Commented Oct 23, 2016 at 17:31
• 1 @torazaburo The proof is in the pudding, was going to make a screen shot when I realized that I had encapsulated the id as a string in my test and in the example here on SO it is an integer. That is the problem, thanks for your help! ;/ – Craig van Tonder Commented Oct 23, 2016 at 17:44

It is working. The console.log might be confusing you:

var rooms = [
  { title: 'Just For Fun', created: '2016-10-23T16:57:03.288Z', id: 2 },
  { title: 'Development', created: '2016-10-23T16:57:03.294Z', id: 6 }
];
var room = _.find(rooms, {'id': 6});
console.log(room); // Object {title: "Development", created: "2016-10-23T16:57:03.294Z", id: 6}
