If we are going to refactor this function I think making it asynchronous would be really beneficial. Currently a lot of the code in helper.js is synchronous and as a good rule of thumb for any I/O this stuff should be async.

I like the readability changes but if we're updating this, we should make it really nice

Yes, there are a lot of stuff which can be run asynchronous.

OK, i can "promisify" this function and change calling code.

Suggested change
return Fs.statSync(path).isDirectory() && Fs.existsSync(`${path}/package.json`)
return Fs.statSync( path ).isDirectory() && Fs.existsSync( `${path}/package.json` )

We might need to put a Path.normalize( ${path}/package.json ) here also
