javascript code CPU Usages

[shahriarcoder]

sometimes my javascript codes takes up to 90% cpu usage.
for example a js like used in HTTP://UIT1.COM (HTTP://WWW.UIT1.COM) a "carousel" js has this problem.
it is a normal website about UltraSound, Transducers and Medical Equipments .
Which factor cause this problem !?

Thanks to all.

Intensive operations can cause intensive CPU usage. Maybe your code has memory leaks or is written inefficiently. Either way, it belongs in the JavaScript forum, not this one.
