If you're not going to name the function, probably the second one – Andy Ray Oct 19 '16 at 02:56

Does the code that will be calling the function need to be able to `.call()`, `.apply()`, or `.bind()` it? – nnnnnn Oct 19 '16 at 03:22

2In the first example, there is no need for the final semi-colon. – Oct 19 '16 at 03:41

The first one is generally preferred. It's a declaration, not an expression value, which has subtle advantages. And it can easily be named if you want, which is a good practice. Also, arrow functions have a few disadvantages in certain situations, so unless you absolutely need them to preserve a this value (etc.) you'd rather avoid them. Saving 5 characters to type is hardly worth it.
