Deleting from localStorage: should I use delete or

问题:

I'm using localStorage in a Chrome extension.

Is there any difference between delete localStorage[key] and window.localStorage.removeItem(key) or do they behave identically?

Note that I choose window.localStorage.removeItem(key) to correspond exactly to the spec, but localStorage.removeItem(key) is how it would probably look in the wild.

There's no difference in Chrome, but i recommend using localStorage.removeItem(key) so that you get in the habit of doing so. That way, when you go to use localStorage in a website, you are already using the method that is most likely to work with shims and polyfills for outdated browsers.
