kumu.js is overriding the prototype of array:<br>
<br>
Array.prototype = Kumu.extend(Array.prototype, {<br>
map:Kumu.map,<br>
filter:Kumu.filter,<br>
shift:Kumu.shift,<br>
unshift:Kumu.unshift,<br>
include:Kumu.include<br>
<br>
});<br>
<br>
which is causing serious performance problems in JavaScript heavy page in IE7,8.<br>
<br>
What's the reason? If kumu.js is trying to deal with legacy browsers without<br>
all these methods provided, at least it should the existence of the methods<br>
before overriding them.<br>
<br>
Any advice or suggestion will be greatly appreciated.<br>
<br>
Best Regards,<br>
<br>
