They try doing something that’s trivial in their day-to-day language, run into problems and assume it’s because functional programming is terrible. Then they ask a pointed, overly detailed ...

Finally, an issue that is not necessarily part of functional programming as a paradigm, but is very important to pay attention to when doing functional programming, is that of variable scope and ...

You could do this: The built-in functions you’ve seen so far are fundamental to functional programming (and its programming-in-the-large sibling, reactive programming). Now, let’s consider the ...

Immutability, a lack of side effects, and composability are some of the features that have recently increased the popularity of functional programming languages, especially in the era of ...

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 ...

"Functional programming languages don't have side effects," he says. "The computational fabric is inherently parallel - if anything you have to do some work to sequentialise it. For the parallel ...
