lodash wrapper to array 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 merge

import merge from 'lodash/merge'

let object = {  'a': [{ 'b': 2 }, { 'd': 4 }]}; 
let other = {  'a': [{ 'c': 3 }, { 'e': 5 }]}; 
merge(object, other); // => { 'a': [{ 'b': 2, 'c': 3 }, { 'd': 4, 'e': 5 }] }

Example 3: loadash date format

_.defer(function(stamp) {  console.log(_.now() - stamp);}, _.now());// => Logs the number of milliseconds it took for the deferred invocation.
