In JavaScript, objects can be used to serve various purposes. | |
To maximise our usage of the type system, we should assign different types to our objects depending | |
on the desired purpose. | |
In this blog post I will clarify two common purposes for objects known as records and dictionaries | |
(aka maps), and how they can both be used with regards to the type system. |
in OS X 10.4 to macOS sierra 10.12 and maybe higher!

There are many tutorials and articles available online which explain functional programming. Examples show small functions, which are composed into others which again get composed. It is hard to imagine how it would all work, then come the analogies and then the math. While the math is necessary to understand it can be difficult to grasp initially. The analogies on the other hand, (at least for me) are not relatable. Some articles assume the reader knows the different terminologies of FP. Over all I felt it is not inviting to learn.
This introduction is for those who have had a tough time understanding those analogies, taken the plunge to functional programming but still have not been able to swim. This is yet another tutorial on functional programming
Functions are first class means they are just like anyone else, or rather they are not special, they behave the same as say primitives or strings or objects.
