Save game feature question

[mrnannings]

So i want to implement a simple save and load feature in my game. After reading some threads i think something like this is sufficient.

 

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

 

But after seeing this about localstorage: https://developer.mozilla.org/en-US/docs/Web/Guide/API/DOM/Storage#localStorage

 

Important: This guide is out-of-date. For up-to-date information on Web Storage, you should visit the Web Storage landing page for reference, and ourUsing the Web Storage API guide for a walkthrough.

 

And i see that store.js also using, i think, this way of saving objects...

 

Well my question is how do i save and load an object the best way and that it is still usable after a while (not deprecated)
