lodash compare objects code example

Example 1: lodash deep compare two objects

var bob = {"sex":"male","age":21};
var bill = {"sex":"male","age":21};
if(_.isEqual(bob, bill)){
    //we are equal
}else{
	//we are not equal
}

Example 2: diff two arrays lodash

_.difference([2, 1], [2, 3]);
// => [1]

Example 3: 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 4: get lodash

var object = { 'a': [{ 'b': { 'c': 3 } }] }; _.get(object, 'a[0].b.c');// => 3 _.get(object, ['a', '0', 'b', 'c']);// => 3 _.get(object, 'a.b.c', 'default');// => 'default'
