The ideal in functional programming is what is known as pure functions. A pure function is one whose results are dependent only upon the input parameters, and whose operation initiates no side ...

I’ll conclude by introducing you to five functional programming techniques. Code examples in these sections will get you started with pure functions, higher-order functions, lazy evaluation ...

Functional programming adopts an entirely different approach. It focuses on data and its transformations using pure functions, which do not depend on any global context. In functional programming ...
