Some languages may allow list types to be indexed or sliced like array types, in which case the data type is more accurately described as an array. In type theory and functional programming, abstract lists are usually defined inductively by two operations: nil that yields the empty list, and cons, which adds an item at the beginning of a list.

The cursor's feature item provides access to each structure element. Descendants of class ITERATION_CURSOR can be created to handle specialized iteration algorithms. The types of objects that can be iterated across (my_list in the example) are based on classes that inherit from the library class ITERABLE.
Rest parameters are similar to Javascript's arguments object, which is an array-like object that contains all of the parameters (named and unnamed) in the current function call. Unlike arguments , however, rest parameters are true Array objects, so methods such as .slice() and .sort() can be used on them directly.
For simplicity, list items in pure wiki markup cannot be more complex than a basic paragraph. A line break in the wikimarkup of a list item will end not just the item but the entire list, and reset the counter on ordered lists.
It is being built into a comprehenisve list of all articles or article sections about JavaScript on Wikipedia. Once it is completed, it will serve as a map of the entire subject's coverage. A JavaScript-experienced editor will be able to spot gaps in that coverage. And the list will also allow monitoring of all JavaScript-related pages.
Objects are the run-time entities in an object-oriented system. They may represent a person, a place, a bank account, a table of data, or any item that the program has to handle. There have been several attempts at formalizing the concepts used in object-oriented programming.
jQuery, a JavaScript library that provides an Ajax framework and other utilities, and jQuery UI, a plug-in that provides abstractions for low-level interaction and animation, advanced effects and high-level, themeable widgets. GPL and MIT: MooTools, a compact and modular JavaScript framework best known for its visual effects and transitions.
JSONP makes sense only when used with a script element. For each new JSONP request, the browser must add a new <script> element, or reuse an existing one. The former option—adding a new script element—is done via dynamic DOM manipulation, and is known as script element injection.
