  2. Immutable object - Wikipedia

    en.wikipedia.org/wiki/Immutable_object

    Immutability does not imply that the object as stored in the computer's memory is unwriteable. Rather, immutability is a compile-time construct that indicates what a programmer can do through the normal interface of the object, not necessarily what they can absolutely do (for instance, by circumventing the type system or violating const ...

  3. Immutable interface - Wikipedia

    en.wikipedia.org/wiki/Immutable_interface

    Concrete classes have to explicitly declare they implement the immutable interface. This may not be possible if the concrete class "belongs to" third-party code, for instance, if it is contained within a library. The object is not really immutable and hence not suitable for use in data structures relying on immutability like hash maps.

  4. Strongly typed identifier - Wikipedia

    en.wikipedia.org/wiki/Strongly_typed_identifier

    C# have records which provide immutability and equality testing. [1] The record is sealed to prevent inheritance. [2] It overrides the built-in ToString() method. [3]This example implementation includes a static method which can be used to initialize a new instance with a randomly generated globally unique identifier (GUID).

  5. Constant (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Constant_(computer...

    In a number of object-oriented languages, there is the concept of an immutable object, which is particularly used for basic types like strings; notable examples include Java, JavaScript, Python, and C#. These languages vary in whether user-defined types can be marked as immutable, and may allow particular fields (attributes) of an object or ...

  6. Liskov substitution principle - Wikipedia

    en.wikipedia.org/wiki/Liskov_substitution_principle

    Liskov's notion of a behavioural subtype defines a notion of substitutability for objects; that is, if S is a subtype of T, then objects of type T in a program may be replaced with objects of type S without altering any of the desirable properties of that program (e.g. correctness).

  7. SpiderMonkey - Wikipedia

    en.wikipedia.org/wiki/SpiderMonkey

    PythonMonkey uses SpiderMonkey to allow users to write programs where JavaScript and Python functions, types, and events interoperate and (where possible) share memory storage. [26] The text-based web browser ELinks uses SpiderMonkey to support JavaScript [27] Parts of SpiderMonkey are used in the Wine project's JScript (re-)implementation [28]

  9. Python syntax and semantics - Wikipedia

    en.wikipedia.org/wiki/Python_syntax_and_semantics

    A snippet of Python code with keywords highlighted in bold yellow font. The syntax of the Python programming language is the set of rules that defines how a Python program will be written and interpreted (by both the runtime system and by human readers). The Python language has many similarities to Perl, C, and Java. However, there are some ...
