# Godzilla: Go running JavaScript
## Overview
Godzilla is a [ES2015](http://babeljs.io/learn-es2015) to Go source code transpiler and runtime that is intended to be a near drop-in replacement for [Node.js](https://nodejs.org).
It compiles ES2015 source code to Go source code which is then compiled to native code.
The compiled Go source code is a series of calls to the Godzilla runtime, a Go library serving a similar purpose to Node.js.Godzilla parses ES2015 source code with the awesome [babylon](https://github.com/babel/babylon).
That means at the moment Node.js is required for compilation.
As Godzilla becomes mature, `babylon` will be compiled to Go source code using Godzilla itself so that the Node.js dependency can be dropped.**Note that Godzilla is at a very early stage and only very few language features are implemented**

## Compiling
Make sure Go and Node.js are installed properly, then run:
```
$ make
```## Running
```
$ echo "console.log('Hello, Godzilla')" | bin/godzilla run
Hello, Godzilla
$ echo "console.log('Hello, Godzilla')" | bin/godzilla build -o hello
$ ./hello
Hello, Godzilla
```## Performance
There are still lots of works to get Godzilla to a stable state, but this is one preliminary benchmark for a simple script about program startup time:
```
$ echo "console.log('Hello, Godzilla')" | bin/godzilla build -o hello
$ time ./hello
Hello, Godzilla
./hello 0.00s user 0.00s system 30% cpu 0.013 total$ echo "console.log('Hello, Godzilla')" > hello.js
$ time node hello.js
Hello, Godzilla
node hello.js 0.07s user 0.03s system 70% cpu 0.137 total
