Using JavaScript Promises to stop render blocking with localStorage

localStorage.async.js

class Storage {
	get(item) {
		const request = new Promise((resolve, reject) => {
			let data = localStorage.getItem(item);
      console.log(`Start of promise`);
			(data) ? resolve(data) : reject();
		});

		request.then((data) => {
      console.log(`promise resolved`);
			console.log(JSON.parse(data));
		});

		request.catch((error) => {
      console.log(`Promise rejected`);
			console.log(error);
		});
	}
	set(name, data) {
		localStorage.setItem(name, JSON.stringify(data));
	}
}

const Store = new Storage;

let test = {
	name: 'test',
	token: '12lj33i237yqekjbfq.183rkjew'
}

Store.set('test', test);

Store.get('test');
