I found this code on Internet:
Code:
 
<script type="text/javascript">

Array.prototype.push = function() {
    var n = this.length >>> 0;
    for (var i = 0; i < arguments.length; i++) {
        this[n] = arguments[i];
        n = n + 1 >>> 0;
    }
    this.length = n;
    return n;
};

</script>
Question 1: How to call this function?
Question 2: When I delete >>> 0, what I lose? ( >>>0 ı sildiğim zaman, ne kaybederim?)
