what is lodash javascript 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

_.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' }    }
