  2. Comparison of programming languages (associative array)

    en.wikipedia.org/wiki/Comparison_of_programming...

    Generic. Dictionary < ' TKey , ' TValue > type (which is implemented as a hash table ), which is the primary associative array type used in C# and Visual Basic. This type may be preferred when writing code that is intended to operate with other languages on the .NET Framework, or when the performance characteristics of a hash table are ...

  3. Dynamic array - Wikipedia

    en.wikipedia.org/wiki/Dynamic_array

    Elements can be removed from the end of a dynamic array in constant time, as no resizing is required. The number of elements used by the dynamic array contents is its logical size or size, while the size of the underlying array is called the dynamic array's capacity or physical size, which is the maximum possible size without relocating data.

  4. Type safety - Wikipedia

    en.wikipedia.org/wiki/Type_safety

    In computer science, type safety and type soundness are the extent to which a programming language discourages or prevents type errors.Type safety is sometimes alternatively considered to be a property of facilities of a computer language; that is, some facilities are type-safe and their usage will not result in type errors, while other facilities in the same language may be type-unsafe and a ...

  6. Observer pattern - Wikipedia

    en.wikipedia.org/wiki/Observer_pattern

    JavaScript has a deprecated Object.observe function that was a more accurate implementation of the observer pattern. [10] This would fire events upon change to the observed object. Without the deprecated Object.observe function, the pattern may be implemented with more explicit code: [11]

  7. Generic programming - Wikipedia

    en.wikipedia.org/wiki/Generic_programming

    A generic unit is a package or a subprogram that takes one or more generic formal parameters. [18] A generic formal parameter is a value, a variable, a constant, a type, a subprogram, or even an instance of another, designated, generic unit. For generic formal types, the syntax distinguishes between discrete, floating-point, fixed-point, access ...

  8. Parametric polymorphism - Wikipedia

    en.wikipedia.org/wiki/Parametric_polymorphism

    The polymorphic definition can then be instantiated by substituting any concrete type for , yielding the full family of potential types. [3] The identity function is a particularly extreme example, but many other functions also benefit from parametric polymorphism.

  9. Object copying - Wikipedia

    en.wikipedia.org/wiki/Object_copying

    In languages without primitive types (where everything is an object), all fields of the copy B are references to the same objects as the fields of original A. The referenced objects are thus shared, so if one of these objects is modified (from A or B), the change is visible in the other. Shallow copies are simple and typically cheap, as they ...
