This is the great part about ReScript, and it also means that before you start using ReScript you currently have to have some knowledge about how JS and the ecosytem works. We probably have some room to add in more tutorials about how to get going for those who are not familiar with JS.
A good example is this note for the ReScript React docs:
This documentation assumes basic knowledge about ReactJS.
Please note that even though we will cover many basic React concepts, it might still be necessary to have a look at the official ReactJS resources, especially if you are a complete beginner with React.
We aren’t teaching or documenting how to use React, just how to use ReScript with React.
I think we need to get some docs/blog posts on the site about how to get started using frameworks that are built using ReScript for ReScript, such as res-x or rescript-rest. These would be good starting points for people who have not worked in the JS ecosystem and are coming to ReScript from other languages and stacks.
