lodash search object for key code example

Example 1: lodash find object in array

var users = [
  { 'user': 'barney',  'age': 36, 'active': true },
  { 'user': 'fred',    'age': 40, 'active': false },
  { 'user': 'pebbles', 'age': 1,  'active': true }
];
 
_.find(users, function(o) { return o.age < 40; });
// => object for 'barney'

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"
//}

Example 3: lodash map

_.each(markets, (obj, key) => {   obj.symbol = key})console.log(markets)//=> {       'BTC/USD': { buys: 0, sells: 3, symbol: 'BTC/USD' },       'DASH/BTC': { buys: 3, sells: 1, symbol: 'DASH/BTC' },       'ETH/BTC': { buys: 3, sells: 2, symbol: 'ETH/BTC' }    }
