Q:  IE throws error: "Object does not support this property or method". What happened?
A:  http://www.prototypejs.org/learn/extensions


Q:  Error is thrown: this.<blah> is not a function. What happened?
A:  This is most likely an execution context (scope) problem. Iterators (which are used in Enumerable methods) 
    and event handlers (used in Element#observe) are executed within global context.
    Changing the execution context is as easy as using Function#bind or Function#bindAsEventListener

Q:  I get all kinds of weird output when iterating over an array using for..in.
A:  for..in should not be used to iterate over arrays

Q:  Something doesn't work as expected. What should I do?
A:  1) Get the latest version of prototype.
    2) Make sure a document has a proper doctype and is valid. http://validator.w3.org/
    3) There could be a conflict with other scripts in a document.
        Try narrowing down the conflicting ones.


Q:  My applications slows down when I use Event#observe on 1000+ cells in a table.
A:  Event delegation could increase performance (and reduce memory usage) in such cases.

Q:  How do I make prototype work together with jQuery?
A:  The easiest way is to use jQuery's noConflict.
    http://docs.jquery.com/Using_jQuery_with_Other_Libraries


Q:  Is it possible to extend elements by criteria other than tagName (e.g. by className or an attribute)?
A:  Not in a current implementation. The extension mechanism is complex enough 
    and such support would most likely lead to unnecessary complexity.


Q:  Script.aculou.us wiki is down. Help!
A:  You could use an offline version of docs.
