Often in web development there is this recurring pattern of having to fetch some data from some server through a rest api, and then show it someway in the UI. This often includes storing this data somewhere on the client side, either in a store or just a variable you can reference, and this is where the Remote Data type can help. Usually saving the data would look something like this in JS:

I have recently been exploring creating web apps in Elm and found it to be a breath of fresh air compared to the usual React/Redux projects I have worked on in the past. *Disclaimer: I still think React/Redux is great and viable for large teams if done correctly. This article will just explain my pain points with it while working on large teams at various companies, and why I think Elm can be a better alternative in some cases.

I recently gave an internal talk at my work about the similarities of F# compared to JS. It was generally well received, and I would like to convert that talk into a blog post for others who may be interested. This is by no means an exhaustive list of features in F#, but the point of this post is to show familiar JS code and how it can be written equivalently in F#, because I believe showing examples like this is the best way of learning a new language and has a better chance of adoption.

I’m going to explain some common monads that you can start using in your javascript today. Monads will help make your code easier to read, more maintainable and most importantly - safer. Maybe The Maybe monad is used for dealing with nullable data. Often we like to process data in javascript, like formatting, doing calculations, filtering and sorting. But often we need to make sure the data is there before doing anything.
