| normalizeUrl('//sindresorhus.com:80/');
 | |
| //=> 'http://sindresorhus.com'
 | |
| 
 | |
| normalizeUrl('//sindresorhus.com:80/', {normalizeProtocol: false});
 | |
| //=> '//sindresorhus.com'
 | |
| ```
 | |
| 
 | |
| ##### forceHttp
 | |
|

 | |
| });
 | |
| //=> 'http://sindresorhus.com/?foo=bar'

| ```
 | |
| 
 | |
| If a boolean is provided, `true` will remove all the query parameters.

| normalizeUrl('www.sindresorhus.com?foo=bar&utm_medium=test&ref=test_ref', {
 | |
| 	removeQueryParameters: false
