Type classIn computer science, a type class is a type system construct that supports ad hoc polymorphism. This is achieved by adding constraints to type variables in parametrically polymorphic types. Such a constraint typically involves a type class T and a type variable a, and means that a can only be instantiated to a type whose members support the overloaded operations associated with T.
Elixir (langage)Elixir est un langage de programmation multi-paradigme fonctionnant sur la machine virtuelle Erlang (BEAM). Il est créé en 2011 par le développeur José Valim, personnalité du monde Ruby et l'un des premiers contributeurs au framework de programmation Ruby on Rails. Il intègre les paradigmes de programmation fonctionnelle, programmation concurrente et , et supporte la métaprogrammation via un système de macros et le polymorphisme via un système dit de protocoles.
This (programmation informatique)this, self, and Me are keywords used in some computer programming languages to refer to the object, class, or other entity of which the currently running code is a part. The entity referred to by these keywords thus depends on the execution context (such as which object is having its method called). Different programming languages use these keywords in slightly different ways. In languages where a keyword like "this" is mandatory, the keyword is the only way to access data and methods stored in the current object.
