Bonus part issues about learn-regex

Also, redundant character class brackets. ( [[a-zA-Z0-9]\-\.] should just be [a-zA-Z0-9\-\.], etc... ). This breaks functionality.

$ node
> /^(((http|https|ftp):\/\/)?([[a-zA-Z0-9]\-\.])+(\.)([[a-zA-Z0-9]]){2,4}([[a-zA-Z0-9]\/+=%&_\.~?\-]*))*$/.test( 'https://github.com/zeeshanu/learn-regex' )
false
> /^(((http|https|ftp):\/\/)?([a-zA-Z0-9\-\.])+(\.)([a-zA-Z0-9]){2,4}([a-zA-Z0-9\/+=%&_\.~?\-]*))*$/.test( 'https://github.com/zeeshanu/learn-regex' )
true
