I was searching an indexOf polyfill for IE8, and I found this question. The accepted answer suggests this code:

if (!Array.prototype.indexOf) {
Array.prototype.indexOf = function(elt /*, from*/)
{
var len = this.length >>> 0;

var from = Number(arguments[1]) || 0;
from = (from < 0)
     ? Math.ceil(from)
     : Math.floor(from);
if (from < 0)
  from += len;

for (; from < len; from++)
{
  if (from in this &&
      this[from] === elt)
    return from;
}
return -1;

}; }

I never see before a triple >:

var len = this.length >>> 0;

What is?
