Fixed some code style inconsistencies in NodeJS example

[SamuelBolduc]

I'm really not sure what are the code standards in the project for NodeJS, but there were some obvious inconsistencies here and there. I fixed those, without changing chosen code styles.

Neither am I! This could benefit from an .editorconfig file and the some code style enforcement. But those are both among many (many) low-priority Fine Uploader-related items on my list at the moment.

Thanks for the contribution. I'll take a closer look soon. The version number in the package.json should be update to indicate that this is a hotfix revision. If you have any other suggestions, do let me know (or open up another PR).

One more thing - have you tested locally to be sure that this doesn't obviously break request handling?

Yup, just tested, everything still works fine.

I bumped the patch version in 423af6f

I agree. When I have the time I might take on that task - it should not be very hard to upgrade the code to actual Javascript style standards.
