检查时如何使元素从html DOM树中消失？

Question

I've learnt that Shadow DOM tree with its elements can be viewed or inspected in developer tools after making some adjustments in settings ( 'show shadow DOM' checkbox).

Is there any way to have element in tree but not visible outside. I mean, JS needs to use that element later.

Element has no visual appearance on the page and will never have. It serves as a DOM container for some information.

You can store variables in local Storage using javascript.

localStorage.setItem(key, value);
localStorage.getItem(key);
