local storage - Is writing the same value to localStorage again inefficient?

Question

Which would be more efficient?

Repeatedly running localStorage.setItem("foo", val), or checking if (localStorage.getItem("foo") !== val) and then running localStorage.setItem("foo", val)? Is it fine to run these as often as every two seconds?
