Beginning Object Oriented javascript' question- Handle Memory leaks in javascript

[pinky suresh]

Hi,

I was reading all the questions related to 'Beginning Object Oriented javascript' book and the following question stike my mind.

Since javascript or any language supports design patterns, I guess there will be some mechanism to avoid memory leaks also.what to we have to avoid memory leaks in javascript?

If i am using javascript in my code and my application becomes slow, what could be the reasons/places that i can check in my js code?

having huge dynamically created javascript arrays make the web applications run very slower. I have experienced this in some applications.And creating lot of objects (text feilds etc...) in the page dynamically also cause the web applications run slower (may be browser's capability of handling more objects).
