Storing Objects in localStorage

local storage limited to handle only string key/value pairs you can do like below using JSON.stringify and while getting value JSON.parse

var testObject ={name:"test", time:"Date 2017-02-03T08:38:04.449Z"};

Put the object into storage:

localStorage.setItem('testObject', JSON.stringify(testObject));

Retrieve the object from storage:

var retrievedObject = localStorage.getItem('testObject');

console.log('retrievedObject: ', JSON.parse(retrievedObject));
