body: <p>I just find from a forum about cascade. The question was what does cascading means in poo. I tried to find to google the answer, also tried to find some other stackoverflow threads about if but I couldn't. I just find this link <a href="http://en.wikipedia.org/wiki/Method_cascading" rel="nofollow">http://en.wikipedia.org/wiki/Method_cascading</a></p>
  
  <p>I know what is chaining, I used it, most in javascript, jquery and other languages, but I coundn't understand the difference between chaining and cascading. Can anybody help me? Or can anybody provide some useful links regarding to this?</p>
