replace some feature from lodash/underscore with pure es6

lodash2es6.js

let monObjet = {name: "moi", job: "dev", city: "lyon"}
let monTableau = [1, "dessert", "soir", ]

become

become 
ee = ((monObjet) => {let {job} = monObjet; return {job}})(monObjet) 
or this shorter version
ee = (({job}) => ({job}))(monObjet) 
and this one with assign 
ee = {}; Object.assign(ee, (({job}) => ({job}))(monObjet))

ee = _.omit(monObject, job, name) 
become 
ee = (({job, name, ...tails}) => (tails))(monObjet)

bool = _.contains(monArray, keyToFind) 
become 
bool = monArray.find(qryParam => qryParam === keyToFind)
