Container (abstract data type) In computer science, a container is a class or a data structure [1][2] whose instances are collections of other objects. In other words, they store objects in an organized way that follows specific access rules. The size of the container depends on the number of objects (elements) it contains.
In computer science, array is a data type that represents a collection of elements (values or variables), each selected by one or more indices (identifying keys) that can be computed at run time during program execution. Such a collection is usually called an array variable or array value. [ 1 ] By analogy with the mathematical concepts vector ...
In an associative array, the association between a key and a value is often known as a "mapping"; the same word may also be used to refer to the process of creating a new association. The operations that are usually defined for an associative array are: [ 3 ][ 4 ][ 8 ] Insert or put. add a new pair to the collection, mapping the key to its new ...

A class defines an implementation of an interface, and instantiating the class results in an object that exposes the implementation via the interface. [3] In the terms of type theory, a class is an implementation—a concrete data structure and collection of subroutines—while a type is an interface. Different (concrete) classes ...
JavaScript and XML. Ajax (also AJAX / ˈeɪdʒæks /; short for " asynchronous JavaScript and XML " [ 1 ][ 2 ]) is a set of web development techniques that uses various web technologies on the client-side to create asynchronous web applications.
