Saving two separate arrays in local storage using JavaScript

Let's say I have two arrays: myFavCars and myDislikedCars. How can I combine them and store in local storage like this:

localStorage.setItem('myPreferences', { myFavCars: [], myDislikedCars: [] })

Is it feasible to store two separate arrays in a single item on local storage?

Answer №1

A possible solution is to use JSON.stringify to convert the data to a string, but keep in mind that it will be in the form of a string and you will need to parse it back to an Object.

localStorage.setItem('mySettings',JSON.stringify({ theme: 'light', language: 'English' }))

To retrieve the information, you can use the following:

const settings = JSON.parse(localStorage.getItem('mySettings'))
