PureScript 是个小巧而强大的静态类型语言，可以编译成 JavaScript。purescript 主要是由 Haskell 和 PureScript 编写的。

PureScript 示例代码：


module Main where
import Debug.Trace
main = trace "Hello, World!"

编译成 JavaScript 代码：


var PS = PS || {};
PS.Main = (function () {
"use strict";
var Debug_Trace = PS.Debug_Trace;
var main = Debug_Trace.trace("Hello, World!");
return {
main: main
};
})();
