Enhance the array object by adding value

I have an array called labels with the values "Hat", "Chair", and "Pen". I am looking to convert this array into an object where each value is set to true, like so:

var output = {"Hat": true, "Chair": true, "Pen": true};

Can someone provide guidance or code on how to achieve this in JavaScript?

Thank you!

Answer №1

To achieve this, you can utilize the .reduce method:

var items = ["Apple", "Banana", "Orange"];

const result = items.reduce((accumulator, element) => {
  accumulator[element] = true;
  return accumulator;
}, {});

console.log(result);

Answer №2

const items = ["Shirt", "Table", "Book"];
let itemsObject = {};
items.forEach(item => {
  itemsObject[item] = true;
})

console.log(itemsObject)
