-Converts a Program `NodePath` into a Javascript code string. The default formatter is `prettier`. The `formatterOptions` object should be [prettier options map](https://prettier.io/docs/en/options.html) or a [babel generator options map](https://babeljs.io/docs/en/next/babel-generator.html#options) depending on which `formatter` is specified.
