Converts a string to a URL-friendly slug.
- Use `String.prototype.toLowerCase()` and `String.prototype.trim()` to normalize the string.
- Use `String.prototype.replace()` to replace spaces, dashes and underscores with `-` and remove special characters.
```js
const slugify = str =>
str
.toLowerCase()
.trim()
.replace(/[^\w\s-]/g, '')
.replace(/[\s_-]+/g, '-')
.replace(/^-+|-+$/g, '');
```
```js
slugify('Hello World!'); // 'hello-world'
```
