Does the Local Storage have some kind of internal "optimization" by the browser?

Question

Is there any difference between:

localStorage.setItem('foo', 1);

and:

localStorage.setItem('foo', true);

From the point of view of storage requirements? Is there any kind of value optimization carried out by the browser before actually storing data (i.e. compression)?

Please note that I'm assuming that Local Storage can handle any type of data and not just strings. I'm not sure about this.

Answer 1

Any non-strings that you store in localStorage are converted to strings before being stored. So true would be stored as "true", and 1 would be stored as "1".
