import { TEMP_CHILD_CLASS } from '.';
import { IsHTMLElement } from './typesCheckers';
export const observeMutation = (callback, element, options, mutationFilter = () => true) => {
    const observe = new MutationObserver((mutations) => {
        mutations = mutations.filter(mutationFilter);
        if (mutations.length > 0) {
            const mutation = mutations[0];
            callback(observe, mutation);
        }
    });
    observe.observe(element, options);
    return observe;
};
export const isTempElement = (element) => {
    if (!IsHTMLElement(element)) {
        return false;
    }
    return element.classList.contains(TEMP_CHILD_CLASS);
};
