Best Functional Programming Tutorials 2020
Most software written today is too complex, difficult to understand, difficult to test, difficult to modify, and full of hard to find bugs.
Ouch! So how do we end up with these problems?
Here are some of the many reasons:
Don’t use the simplest building blocks possible… If you start with something complicated, you will end up with something even more complicated.
Programming in a style more sensitive to complex bugs
Failure to respect and properly manage side effects (talking to servers, entry / exit, etc.)
Sprinkling Application State all through codebases
Data in unnecessary mutation
Code duplication (particularly sneaky, like similar class methods in object-oriented programming)
Write more code than necessary
These are just a few of the many issues that lead to frustrating tasks, working on hard-to-maintain code bases, and adding functionality.
Functional programming solves the above problems as follows:
Simpler applications, because functional programming uses the simplest building blocks possible, just old data and pure functions to transform data (easier to understand and use)
Uses simpler code styles and less prone to complicated bugs (more time for productive work)
Eliminate side effects as much as possible and control them when needed (reduces bugs)
Avoid data mutation as much as possible (reduce bugs)
Uses pure functions, which can work with many types of data (improved code reuse)
Uses generalized functions, which can be specialized to meet different needs (less code, same functionality)
Create new functions, without adding new logic, using function composition (more functionality, no added code)
Functional programming, in my experience, is more productive than object-oriented programming because there is less to think about, so you don’t overwhelm your working memory. Usually you just think of old data and data transformations using functions. Also, in functional programming there aren’t tons of competing ways to do the same thing, so you don’t have to think about unnecessary things. Functional programming is binding and that’s a good thing. You can focus better, on the problem you are solving, rather than on the tools you are using to solve the problem.
In object-oriented programming, you have to think about many different types of complex and stateful objects that you can interact with in different ways. You have to think about more than data and the transformation of data … You have to think about things like condition and side effects, much more than functional programming.
