lodash compare arrays 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: 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 3: diff two arrays lodash

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

Example 4: lodash compare array without order

var array1 = [['a', 'b'], ['b', 'c']];
var array2 = [['b', 'c'], ['a', 'b']];
_.isEqual(array1.sort(), array2.sort()); //true
