Get the query string(s)

readme.md

Usage

// index.html?keywords=test

qs(); // { name: 'keywords', values: [ 'test' ] }

But wait, why store the value in an array?

Because of

// index.html?category=4&category=5&category=6

qs(); // { name: 'category', values: [ '4', '5', '6' ] }

which is a perfectly valid use of query strings.

Also

qs('category'); // [ '4', '5', '6' ]
