lodash filter object by property value code example

Example 1: Lodash remove duplicates from array

var users = [
  {id:1,name:'ted'},
  {id:1,name:'ted'},
  {id:1,name:'bob'},
  {id:3,name:'sara'}
];
var uniqueUsersByID = _.uniqBy(users,'id'); //removed if had duplicate id
var uniqueUsers = _.uniqWith(users, _.isEqual);//removed complete duplicates

Example 2: lodash filter object keys

var user = {
  "first_name":"taylor",
  "last_name":"hawkes",
  "full_name": "taylor hawkes"
};

var userCleaned = _.pickBy(user, function(value, key) {
  return (key === "first_name" || key === "last_name");
});

//userCleaned is now:
//{
//   "first_name": "taylor",
//   "last_name": "hawkes"
//}
