   * 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';

   * 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) => {
