/**
 * Takes a hash and removes all the `undefined`/`null` values from it.
 * In PixiJS, we tend to null properties instead of using 'delete' for performance reasons.
 * However, in some cases, this could be a problem if the hash grows too large over time,
 * this function can be used to clean a hash.
 * @param hash - The hash to clean.
 * @returns A new hash with all the `undefined`/`null` values removed.

/**
 * Removes all `undefined`/`null` elements from the given array and compacts the array.
 *
 * This function iterates through the array, shifting non-undefined elements to the left
 * to fill gaps created by `undefined` elements. The length of the array is then adjusted
 * to remove the trailing `undefined` elements.
 * @param arr - The array to be cleaned.
 * @returns The cleaned array with all `undefined` elements removed.
 * @example
 * // Example usage:
 * const arr = [1, undefined, 2, undefined, 3];
 * const cleanedArr = cleanArray(arr);
 * console.log(cleanedArr); // Output: [1, 2, 3]
