/**
* Executes a function on selected elements repeatedly until the condition is met.
*
* @param {string|Element|NodeList|Array<string|Element|NodeList>} selector - The CSS selector, element, NodeList, or an array containing a combination of these types to select the elements.
* @param {function(Element): boolean} check - A function that checks if the condition is met for an element. It should return `true` if the condition is met and `false` otherwise.
* @param {function(Element): void} fn - The function to be executed on each element that meets the condition.
* @param {number} [interval=50] - The interval in milliseconds between each check of the elements.
*
* @example
* // Example usage with CSS selector
* perma('.example-class', (el) => el.textContent !== 'Example', (el) => {
*   el.textContent = 'Example';
* });
*
* @example
* // Example usage with element
* const element = document.querySelector('#example-id');
* perma(element, (el) => el.classList.contains('active'), (el) => {

/**
* Waits for specific elements to be present in the DOM and executes a callback function when they are found.
*
* @param {string|Element|NodeList|Array<string|Element|NodeList|function(): Element|null>} [selectors=['html']] - The CSS selector(s), element(s), NodeList(s), or array function(s) that return an element or null. Can be a single selector, element, NodeList, array function, or an array containing a combination of these types. Defaults to ['html'] if not provided.
* @param {function(Element): void} [callback=null] - The callback function to be executed when the specified elements are found. It receives the first found element as an argument. If not provided, the function will resolve without executing a callback.
* @param {number} [slow=0] - The delay in milliseconds before executing the callback function. If set to 0 (default), the callback will be executed immediately after the elements are found.
*
* @returns {Promise<void>} A promise that resolves when the specified elements are found and the callback function (if provided) has been executed.
*
* @example
* // Example usage with a single CSS selector
* when('.example-class', (element) => {
*   console.log('Element found:', element);
* });
*
* @example
* // Example usage with multiple CSS selectors
* when(['.example-class', '#example-id'], (element) => {
