Example 1: import lodash
// import entire library
import _ from "lodash"
const nums = [1, 2, 2, 3, 1, 4]
let res = _.uniq(nums)
// import methods by name
// Still loads entire lodash library!!
import { uniq } from "lodash"
const nums = [1, 2, 2, 3, 1, 4]
let res = uniq(nums) // better readability
// import only what you need
import uniq from "loadash/uniq"
const nums = [1, 2, 2, 3, 1, 4]
let res = uniq(nums)
Example 2: lodash npm
$ npm i -g npm
-----------------------
$ npm i --save lodash
Example 3: lodash map
const _quote_filter = _.map(quote_state, (val, key) => { if (val) { return key }})console.log(_quote_filter) //=> [ 'btc', undefined, undefined ]
Example 4: 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 5: 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'
Example 6: node lodash documentation
$ npm i -g npm$ npm i --save lodash
