In this blog post, we look at two ReasonML data structures – lists and arrays:

Variant types (short: variants) are a data type supported by many functional programming languages. They are an important ingredient in ReasonML that is not available in C-style languages (C, C++, Java, C#, etc.). This blog post explains how they work.

In this blog post, we explore how modules work in ReasonML.

This blog post explores how functions work in ReasonML.

In this blog post, we look at three features that are all related to pattern matching: destructuring, switch, and if expressions.

In this blog post, we look at how to introduce new variables and scopes in ReasonML.

In this blog post, we’ll look at ReasonML’s support for booleans, integers, floats, strings, characters and the unit type. We’ll also see a few operators in action.

To explore, we’ll use the interactive ReasonML command line rtop, which is part of the package reason-cli (the manual explains how to install it).

In this blog post, I take a different approach to explaining this in JavaScript: I pretend that arrow functions are the real functions and ordinary functions a special construct for methods. I think it makes this easier to understand – give it a try.

This blog post describes how for-await-of handles synchronous iterables. for-await-of is a core construct of asynchronous iteration. You can read up on it in the blog post “ES proposal: asynchronous iteration”.

This blog post takes a brief look of a few key pieces of ReasonML that are still being worked on:
