<h3 id="how-it-works"><a href="#how-it-works">How it works</a></h3>
<p>The <code>m.parseQueryString</code> method creates an object from a querystring. It is useful for handling data from URL</p>
<pre><code class="lang-javascript">var data = m.parseQueryString("a=hello&b=world")
// data is {a: "hello", b: "world"}
</code></pre>
<h4 id="boolean-type-casting"><a href="#boolean-type-casting">Boolean type casting</a></h4>
<p>This method attempts to cast boolean values if possible. This helps prevents bugs related to loose truthiness and unintended type casts.</p>
<pre><code class="lang-javascript">var data = m.parseQueryString("a=true&b=false")
// data is {a: true, b: false}
</code></pre>
<h4 id="leading-question-mark-tolerance"><a href="#leading-question-mark-tolerance">Leading question mark tolerance</a></h4>
<p>For convenience, the <code>m.parseQueryString</code> method ignores a leading question mark, if present:</p>
<pre><code class="lang-javascript">var data = m.parseQueryString("?a=hello&b=world")
// data is {a: "hello", b: "world"}
</code></pre>
<h4 id="deep-data-structures"><a href="#deep-data-structures">Deep data structures</a></h4>
<p>Querystrings that contain bracket notation are correctly parsed into deep data structures</p>
<pre><code class="lang-javascript">m.parseQueryString("a[0]=hello&a[1]=world")
// data is {a: ["hello", "world"]}
</code></pre>
