Another tenet of functional programming philosophy is not to modify data outside the function. In practice, this means to avoid modifying the input arguments to a function. Instead, the return ...

It’s just like “normal” programming, but… you can’t modify variables… you can’t print… you can’t use mutable data structures. But no. Functional programming isn’t what it isn’t.

Functional programming relies on pure functions and avoids shared state and mutable data. It’s a programming style that rose to prominence with languages like Clojure, Scala, and Elm ...

The bane of many programs, especially concurrent and network programs, is the fact that data changes in unexpected ways. Functional programming advocates keeping most of your data immutable.

Very briefly, the main difference between the two models is that in functional programming data is immutable and functions are 'pure' by default, meaning that they will always return the same ...

In this functional programming tutorial, we will work through a Java Supplier interface example. Java’s functional supplier interface can be used any time a function needs to generate a result without ...
