lodash equals code example

Example 1: lodash deep clone object

const clone = require('lodash/clone'); 
const cloneDeep = require('lodash/clonedeep');

const shallowCopy = clone(originalObject);
const deepCopy = clonedeep(originalObject);

Example 2: 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 3: 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 4: lodash map

const _quote_filter = _.map(quote_state, (val, key) => {   if (val) {      return key   }})console.log(_quote_filter) //=> [ 'btc', undefined, undefined ]
