You might, Why the hell we need another type-safe and fast "language", "tool", and "etc" (You name it) Since typescript already playing a big role in the React community. Well that's was my concern as well, I also came from Typescript + React world. But in reality, ReasonML is not only about the type-safe (The biggest selling point), there are more than that ex: immutability, pattern matching, data structures.
What is ReasonML?

Let's get started with ReasonReact
One of the key players is BuckelScript (Now this has been rebranded as ReScript), this will compile all ReasonML into Js. First, we have to install BuckelScript globally.
npm install --global bs-platform
The fastest way to get started is by using a theme of BuckelScript build system (bsb). First, we have to init the project with a theme of your choice.
bsb -init my-app -theme react-starter
You can list available themes with following command.
For this example, we are using it as the theme. This will generate a ReasonReact minimal project with state and hook.
You can build and run the project with the following commands. Also, this theme Webpack support out of the box.
yarn start & yarn server
Try yourself and see how all of this works. Specially pay attention on how everything has wired up. In next lessons will deep dive into Functional Programming, ReasonML and BuckelScript (ReScript) and how ReasonML help you to develop with confident.
