The Prototype JavaScript Framework is a JavaScript framework created by Sam Stephenson that provides an Ajax framework and other utilities. It is implemented as a single file of JavaScript code, usually named prototype.js. Prototype is distributed standalone, but also as part of larger projects, e.g. Ruby on Rails, script.aculo.us and Rico. Prototype provides various functions for developing JavaScript applications. The features range from programming shortcuts to major functions for dealing with XMLHttpRequest. Prototype also provides library functions to support classes and class-based objects, something the JavaScript language does not have. In JavaScript, object creation is prototype-based instead: an object creating function can have a prototype property, and any object assigned to that property will be used as a prototype for the objects created with that function. The Prototype framework is not to be confused with this language feature.   [edit]  Less
