Is it possible to store integer value in localStorage like in Javascript objects and extract it without typecasting?

When I assign integer value to localStorage item

localStorage.setItem('a',1)

and check its type

typeof(localStorage.a)
"string"

it returns string, I can typecast it to int for my use

parseInt(localStorage.a)

My question is it possible to store integer value inside localStorage as I can do for Javascript objects without typecasting?

a={};
a.number=1;
typeof(a.number)
"number"

No.

Storage objects are simple key-value stores, similar to objects, but they stay intact through page loads. The keys can be strings or integers, but the values are always strings. [source]
