# Developing with go and a JavaScript REPL

This is a demonstration of creating a simple middle-ware and JavaScript REPL based on [otto](https://github.com/robertkrimen/otto) JavaScript implementation, [ostdlib](https://github.com/caltechlibrary/ostdlib) and the [weather.gov REST API](http://graphical.weather.gov/xml/rest.php).  It assumes you're either following along verbatim or you've gone through the Go language tutorials at [golang.org](http://golang.org).

Why Go and a JavaScript REPL?  Well Go is fun, compiles reasonable fast but is not an interpreted dynamically typed language. JavaScript is an interpreted dynamically typed language.  I have found doing ad-hoc or exploratory coding to benefit from the immediate feedback and flexibility found in interpreted dynamically typed laugange. On the other hand when I want things to "just work" and be solid I like Go.  Fortunately Go and JavaScript lively happily together thanks to Robert Krimen's Go package named otto.
