# JS.scala

JS.scala compiles JavaScript code to Scala, allowing you to write your web application entirely in JavaScript!

*Input*

    const a = 42

    const b = "Hello, World"

    const sq = x => x * x

    const dsq = x => {

      const dx = sq(x)

      return dx * dx

    };

    const d = dsq(a)

    const exclaimer = {

      apply: name => name + "!"

    }

    exclaimer.apply("Hello, World")

*Output*

    val a = 42

    val b = "Hello, World"

    def sq (x:HandHolder) = x * x

    def dsq (x:HandHolder) = {

      val dx = sq(x)

      dx * dx

    }

    val d = dsq(a)

    object exclaimer {

      def apply (name:HandHolder) = name + "!"

    }

    exclaimer("Hello, World")

## Types

Next step is to add Flow type inference (https://github.com/facebook/flow) types to AST to restrict the expressive power of JavaScript, but export valid Scala. For now it just replaces types with a "HandHolder" place holder.
