What is the method for retrieving a specific value from an array of objects stored in local storage?

https://i.sstatic.net/812uw.png

Hello there! I'm trying to figure out how to access the title value within my array of objects. Whenever I click the "Add movie" button, I need to check if the movie title is already stored in local storage. If it's found, I want to display an alert saying "Movie already exists".

Answer №1

Accessing the title of a single element directly is not possible. You must retrieve all the movies and then handle it like a regular array. Once you have it, you can use Array#filter or Array#find

Alternatively, if you anticipate growth, consider redesigning your schema similar to organizing a database (which it essentially is ^^)

Answer №2

If you need to check for the existence of an object with a specific title, you can utilize the Array#some method.

const arr = [{title: 'Harry Potter'}, {title: 'Hobbit'}, {title: 'Percy Jackson'}];
const titleExists = title => arr.some(x => x.title === title);
console.log(titleExists('Hobbit'));
console.log(titleExists('Who knows?'));
