 * 3. Removes all non-word characters, spaces, and hyphens using the regex /[^\w\s-]/g.
 * 4. Replaces one or more spaces, underscores, or hyphens with a single hyphen using the regex /[\s_-]+/g.
 * 5. Removes hyphens from the start and end of the string using the regex /^-+|-+$/g.
 *
 * @param {string} str - The string to convert into a slug.
 * @returns {string} The slugified string.

 * slugify('Hello World!');
 * // => 'hello-world'
