What the different between ReasonReact.string and React.string

[fahmiirsyadk]

im new in ReasonReact , when i try the code from intro example

its using ReasonReact

[@react.component]
let make = (~name) =>
  <button> {ReasonReact.string("Hello " ++ name ++ "!")} </button>;

but when i lookup on the component page, its using React instead ReasonReact

[@react.component]
let make = (~name) => {
  let (count, setCount) = React.useState(() => 0);

  <div>
    <p> {React.string(name ++ " clicked " ++ string_of_int(count) ++ " times")} </p>
    <button onClick={_ => setCount(_ => count + 1)}>
      {React.string("Click me")}
    </button>
  </div>
};

i'm super exited to learn ReasonReact <3

Here's what I found from the source:

reason-react/src/React.re

Line 5 in 9df84d2

external string: string => element = "%identity";

reason-react/src/ReasonReact.re

Line 11 in 9df84d2

external string: string => reactElement = "%identity";

I'm also curious about the difference between ReasonReact and the new React module .

EDIT: It seems like they are the same thing, from #360 (comment),

Just in case you didn’t notice, ReasonReact.reactElement is just an alias for React.element.

ohh its look like they wanna migrate to the new API

The Record API is in feature-freeze. For the newest features and better support going forward, please consider migrating to the new function components.

This release also makes use of a new React namespace for APIs for all of the code related to this new way of writing components. 
Some functions have been copied over (like React.string, React.array) and many are new (like hooks)!

There's no difference, it's just shorter and exists in the new namespace. The old APIs are in feature freeze so you probably just want to use React.string instead.
