Clarify answer about functions in question 10

[RinatValiullov]

I think it would be more informative to clarify that functions are first-class objects in question 10th: https://github.com/lydiahallie/javascript-questions#10-what-happens-when-we-do-this

@RinatValiullov What is the difference between objects and first-class objects in JavaScript according to you? I'm asking this just to know what information we will gain.

[RinatValiullov]

Hope this will explain better than me: First-class citizen

Compare to other languages it become valuable (just for clarification). But you can leave as objects

[A1rPun]

If someone is coming from another language it will add some value, I agree.
