So, PHP can have non-consecutively numerically indexed arrays. The keys have to be of integer (floating point numbers are truncated to integer) or string type, while values can be of arbitrary types, including other arrays and objects. The arrays are heterogeneous: a single array can have keys of different types.
A multimap generalizes an associative array by allowing multiple values to be associated with a single key. [9] A bidirectional map is a related abstract data type in which the mappings operate in both directions: each value must be associated with a unique key, and a second lookup operation takes a value as an argument and looks up the key ...
An associative container uses an associative array, map, or dictionary, composed of key-value pairs, such that each key appears at most once in the container. The key is used to find the value, the object, if it is stored in the container. Associative containers are used in programming languages as class templates.
In computer science, a skip list (or skiplist) is a probabilistic data structure that allows () average complexity for search as well as () average complexity for insertion within an ordered sequence of elements. Thus it can get the best features of a sorted array (for searching) while maintaining a linked list-like structure that allows ...
a collection of multiple elements, each identified by an array index, also known as a key. Array constructor a programming constructor used to create array objects in JavaScript. Array literal an array with values fixed in the source code. Array objects created by array literals may also be modified later on. Multi-dimensional array an array ...
Jasmine is an open-source testing framework for JavaScript. [4] It aims to run on any JavaScript-enabled platform, to not intrude on the application nor the IDE , and to have easy-to-read syntax. It is heavily influenced by other unit testing frameworks, such as ScrewUnit, JSSpec, JSpec, and RSpec .
A tabular data card proposed for Babbage's Analytical Engine showing a key–value pair, in this instance a number and its base-ten logarithm. A key–value database, or key–value store, is a data storage paradigm designed for storing, retrieving, and managing associative arrays, and a data structure more commonly known today as a dictionary or hash table.
The Any operator checks, if there are any elements in the collection matching the predicate. It does not select the element, but returns true if at least one element is matched. An invocation of any without a predicate returns true if the collection non-empty. The All operator returns true if all elements match the predicate. Contains
