Problems
Unlike other JavaScript libraries like jQuery, Prototype extends the DOM, but there are plans to change this in the next major version of the library.
In April 2010, blogger Juriy 'kangax' Zaytsev (of Prototype Core) described at length the problems that can follow from adding new methods and properties to the objects defined by the W3C DOM. These ideas echo thoughts published in March 2010 by Yahoo! developer Nicholas C. Zakas They have been summarised as follows
- Cross browser issues: host objects have no rules, IE DOM is a mess, etc.
- Chance of name collisions
- Performance overheads
By 2008, specific issues with using DOM-extension methods in older versions of Prototype, combined with newer versions of current browsers, were already being documented. Rather than adding new methods and properties to pre-existing 'host' DOM objects such as Element, like element.hide, the solution to these issues is to provide wrapper objects around these host objects and implement the new methods on these. jQuery is such a wrapper object in the library of that name.
It is now widely expected that the majority of these ideas and issues will be addressed in the release of Prototype 2.0, but Prototype developers will have to learn to work with an altered syntax, and much existing Prototype code will become outdated.

Famous quotes containing the word problems:
“Belonging to a group can provide the child with a variety of resources that an individual friendship often cannot—a sense of collective participation, experience with organizational roles, and group support in the enterprise of growing up. Groups also pose for the child some of the most acute problems of social life—of inclusion and exclusion, conformity and independence.”
—Zick Rubin (20th century)
“I rarely speak about God. To God, yes. I protest against Him. I shout at Him. But to open a discourse about the qualities of God, about the problems that God imposes, theodicy, no. And yet He is there, in silence, in filigree.”
—Elie Wiesel (b. 1928)
“I was a wonderful parent before I had children. I was an expert on why everyone else was having problems with theirs. Then I had three of my own.”
—Adele Faber (20th century)
