how to use babel transpiler in ruby

Hi,

I am novice to ruby also es6

have created file foo.es6 which contains below code

```
class View {
constructor(options) {
this.model = options.model;
this.template = options.template;
}

render() {
return _.template(this.template, this.model.toObject());
}
}

```

in ubuntu command line
sudo gem install babel-transpiler
-which installed babel-gem

then running ruby file esjs.rb

```
require 'babel/transpiler'
Babel::Transpiler.transform File.read("foo.es6")
```

will this convert es6 to js??

Start with esjs.rb and foo.es6, focusing on the Babel::Transpiler.transform call and the input file it reads. Confirm the expected transformed-JavaScript output and document the usage if this workflow is supported; done when a newcomer can follow the steps and verify the result.
