ReScript is a robustly typed language that compiles to efficient and human-readable JavaScript. It comes with a lightning fast compiler toolchain that scales to any codebase size.


Example from the web:
module Button = { @react.component let make = (~count: int) => { let times = switch count { | 1 => "once" | 2 => "twice" | n => Belt.Int.toString(n) ++ " times" } let msg = "Click me " ++ times <button> {msg->React.string} </button> } }
Example from hello-world:
Js.log("Hello World")
