Url query string in fetch api in javascript
<p>How to pass query string with <code>fetch</code> api javascript (<a href="https://github.com/github/fetch" rel="noreferrer">https://github.com/github/fetch</a>)?</p>

<pre><code>var url = "http://www.abcd.com";
var query = {
    a: "test",
    b: 2
};
</code></pre>

<p>Above should be converted to <code>http://www.abcd.com?a=test&amp;b=2</code> when I pass some argument to <code>fetch</code></p>
