<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=language-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=language-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=language-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=language-javascript>m.parseQueryString("a[0]=hello&a[1]=world")
// data is {a: ["hello", "world"]}</code></pre>
