lodash docs code example

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 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: how to make modules structure like lodash

// ShoppingCartCount.jsx
import { pluralize } from 'utils';

export function ShoppingCartCount({ count }) {
  return (
    <div>
      Shopping cart has {count} {pluralize('product', count)}
    </div>
  );
}

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
