How to assign keys to an object converted from array?

Question

I have the following structure and I would like to change keys name from this

let FIELDS = ['id', 'first_name', 'last_name', 'email']
let {...obj} = ['123','John','Doe', null]
console.log(obj) //  {0: '123', 1: 'John', 2: 'Doe', 3: null}

to something like this

console.log(obj) //  {id: '123', first_name: 'John', last_name: 'Doe', email: null}

Answer 1

I would use Object.fromEntries

const fields = ['id', 'first_name', 'last_name', 'email']
const values = ['123', 'John', 'Doe', null]

const object = Object.fromEntries(fields.map((f, i) => [f, values[i]]))

console.log(object)
