lodash generate 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 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' } }
Example 3: 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'
