JS creating multi value objects array from an array

Question

Trying to get this ['Team Instinct', 'Team Valor', 'Team Mystic']

To this

[{
    answer: "Team Instinct",
    id: asdfsodijha120-938a //nanoid()
 },
 {
    answer: "Team Valor",
    id: 12390i1-293-12093a2 //nanoid()
 },
 {
    answer: "Team Mystic",
    id: 123908320i09i09ss8a //nanoid()
 }
]

What i tried so far

const { nanoid } = require("nanoid")

const array = ['Team Instinct', 'Team Valor', 'Team Mystic']
let object = {}

obcject = array.reduce((prevValue,currentValue) => {
    prevValue.push({
        answer: currentValue,
        id: nanoid()
    })
},[])

ERROR I GET TypeError: Cannot read properties of undefined (reading 'push')

Answer 1

Orig answer is correct, you're missing the return. However, here's an alternate way of writing it

const { nanoid } = require("nanoid")
let object = ['Team Instinct', 'Team Valor', 'Team Mystic'].reduce((prevValue, currentValue) => ([...prevValue, {
  answer: currentValue,
  id: nanoid()
}]), [])

Answer 2

When you use a reducer You lust return the value after pushing in it.

So first error, you never return the result in the callback function. The seconde one, is that you trying then to assign the result of the reduce (an array) to an object.

const { nanoid } = require("nanoid");

const array = ['Team Instinct', 'Team Valor', 'Team Mystic'];

const result = array.reduce((prevValue,currentValue) => {
    prevValue.push({
        answer: currentValue,
        id: nanoid()
    });
    return prevValue;
},[]);
