Using localstorage.clear() but exclude 1 item

Question

I have a lot of items in localstorage, and I want to clear them all...except 1 item, we'll call it "X".

Is there a way to call localstorage.clear() but exclude X?

Store the value you'd like to keep in another variable, then use localStorage.clear()

Example:

var myItem = localStorage.getItem('key');
localStorage.clear();
localStorage.setItem('key',myItem);

Example was taken from this SO post.

... and of course add the variable back to the localStorage once you've cleared it. – HaukurHaf Dec 02 '14 at 20:52
