In this kata you should find BB-tags (bulletin board tags) in given string.
BB-tags look like:
[B]Some content[/B],
where [B] - opening tag and [/B] - closing tag.
Name of tags also can be lowercase:
[url]Some content[/url]
And BB-tags can be nested into each other, for example:
[url][b][size=5][color=blue]Some content[/color][/size][/b][/url]
If there is nested BB-tags, you should return only the outer tag with all it's content (with another tags into it).
function test(str) {
return (str.match(/\[([a-zA-Z]+)](.*)\[\/\1]/g)).join('');
