30-seconds-of-code: Swap values of two variables

[fejes713]

This is not a function really. It's just a tip on how to swap values of 2 variables. However, it is really useful for someone who is new to ES6 syntax.

Both @Chalarangelo and me think that _30-seconds-of-code_ should be consistent and focus only on functions and with that in mind swap values of two variables doesn't really fit in here.

What do you think about the whole situation with it? Should we keep it?

[Chalarangelo]

Like I said on gitter, we should probably remove it. It's a useful tip, but we want functions to work as-is (and be functions actually), so I suggest we get rid of it.

[fejes713]

I taught about making a function that does it but it doesn't make sense since syntax already allows for it very easily. I also think we should remove it.

[Chalarangelo]

Ok, I'm closing and removing the snippet. We should be fine with that.
