Typo in instructions:

Create a route handler with mountainRangesHandler to send back the mountainRanges array in response to a GET /mountainRanges request.

but it should be app.use(’/mountain-ranges’, mountainRangesRouter)


Can’t say for certain but surely Express.js recognizes camelCase and converts to hypenated.


No, it’s not. And there’s no reason why it should be converted by default.


Can’t think of an example right now but I’m sure we come across this in React.js. Pity I’ve not gone down that road very far and dipped my toes into the water so many months ago. For all I know it could have been Rails. No real matter. Maybe a coach will pipe in on this topic being as it is in the Guide.
