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 ...

Meta-programming, lazy evaluation, and type safety are much more common idioms in the functional languages I’ve seen too. These differences mean that doing simple things like iterating over a loop and ...

"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 ...
