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Prototype developers will have to learn to work with an altered syntax, and much existing Prototype code will become outdated.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:
“I believe that if we are to survive as a planet, we must teach this next generation to handle their own conflicts assertively and nonviolently. If in their early years our children learn to listen to all sides of the story, use their heads and then their mouths, and come up with a plan and share, then, when they become our leaders, and some of them will, they will have the tools to handle global problems and conflict.”
—Barbara Coloroso (20th century)
“I have said many times, and it is literally true, that there is absolutely nothing that could keep me in business, if my job were simply business to me. The human problems which I deal with every day—concerning employees as well as customers—are the problems that fascinate me, that seem important to me.”
—Hortense Odlum (1892–?)
“I had many problems in my conduct of the office being contrasted with President Kennedy’s conduct in the office, with my manner of dealing with things and his manner, with my accent and his accent, with my background and his background. He was a great public hero, and anything I did that someone didn’t approve of, they would always feel that President Kennedy wouldn’t have done that.”
—Lyndon Baines Johnson (1908–1973)
