lodash object map code example
Example 1: 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 2: lodash map
const _quote_filter = _.map(quote_state, (val, key) => { if (val) { return key }})console.log(_quote_filter) //=> [ 'btc', undefined, undefined ]
Example 3: 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 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'
