In mathematical terms, an associative array is a function with finite domain. [1] It supports 'lookup', 'remove', and 'insert' operations.

The languages which do so include Ruby, Smalltalk, Python, PHP, Objective-C, Delphi, Java, and the .NET family of languages. There are also libraries available that add serialization support to languages that lack native support for it.
Wilson loops fall into the broader class of loop operators, with some other notable examples being 't Hooft loops, which are magnetic duals to Wilson loops, and Polyakov loops, which are the thermal version of Wilson loops.
Iterator. In computer programming, an iterator is an object that progressively provides access to each item of a collection, in order. [1] [2] [3] A collection may provide multiple iterators via its interface that provide items in different orders, such as forwards and backwards. An iterator is often implemented in terms of the structure ...
