Converting flat array to Id and Name object array using Lodash

Question

let states = ["Georgia","California","FL","TX","MA","NJ"];

How do I convert the states array into Id and Name array collection using lodash.

Is there a way to convert the array in below format ( image shown below):

Answer 1

You don't really need lodash to do that.

 let states = ["Georgia","California","FL","TX","MA","NJ"]; let result = states.map((item) => { return { id: item, name: item}}) console.log(result)

You do pretty much the same with lodash

import _ from 'lodash';

result = _.map(states, (item) => {
return {
      id: item,
      name: item}})

Answer 2

 let states = ["Georgia","California","FL","TX","MA","NJ"]; const newObj = []; _.each(states, state => newObj.push({ id: state, name: state })); console.log(newObj);

_.each performs a function on each item of an Array. With that you can create a new object for each state and push that into a new Array. Note: this could also be accomplished with JavaScript's built in .map .

----- UPDATE ----- Why did I make this complicated many years ago?

 const states = ["Georgia","California","FL","TX","MA","NJ"]; const newObj = states.map(state => ({ id: state, name: state })); console.log(newObj);

No need to use lodash , just map through the array and return a new object for each item in the array.
