expected ';' and instead saw '=' : <p>i have many problems</p>

<p>**very long code is that just a part and stackoverflow limiterd 30000 characters ** </p>

<p><em>first problem</em> :</p>

<p><strong>expected ';' and instead saw '='.</strong></p>

<pre><code>var qq = function(a) {
    "use strict";
    return {
        hide: function() {
            return a.style.display = "none", this
        },
        attach: function(b, c) {
            return a.addEventListener ? a.addEventListener(b, c, !1) : a.attachEvent &amp;&amp; a.attachEvent("on" + b, c),
                function() {
                    qq(a).detach(b, c)
                }
        }
    }
};
</code></pre>

<p><em>other problems</em></p>

<p><strong>unreachable '=' after 'return'.</strong></p>

<p><strong>expected an identifier and instead saw '='.</strong></p>
