Note that the term object in this definition does not necessarily imply an object in an object-oriented language. Although most imperative languages do not contain first class functions, they pr ...

The gist of side effects in pure functional languages
... Purity is not at odds with computations that require side effects like input-output, destructive updates, concurrency, exceptions, or language inter-operation. How is this possible? It is well-known that expressions in pure functional languages are referentially transparent so variables are immutabl ...
