tips for converting objects into arrays with JavaScript

I have an object and I would like to convert it into an array

const object1 = {
  a: { hide:true},
  b:{}
};

I am currently using Object.entries to perform the conversion, however, I am struggling with understanding how it should be done.

Object.entries(object1)

Output:

[{a:{hide:true}},{b:{}}]

Answer №1

If you want to achieve the desired result, you should iterate through the return value of Object.entries and create an object for each element.

const obj = {
  one: { flag:true},
  two:{}
};

let result = Object.entries(obj).map(item=> Object.fromEntries([item]))

console.log(result)

Answer №2

One way to associate the entries with their corresponding objects is by mapping them together.

const
    data = { x: { visible: true }, y:{} },
    output = Object
        .entries(data)
        .map(pair => Object.fromEntries([pair]));

console.log(output);

Answer №3

The reason for this is that the attributes of your item are actually objects themselves.

Both attributes a and b are represented as objects enclosed in curly brackets.

Answer №4

Utilize the map function along with Object.entries and destructuring to manipulate and return the object within the map function.

const data = {
  firstName: 'John',
  lastName: 'Doe'
};

const result = Object.entries(data).map(([key, value]) => ({[key]: value}))

console.log(result)
