07-string-reverse-solition.js

Just another way to reverse a string.

I'm interested in figuring out which is more efficient.

Part of that involves figuring out what array.reverse() does under the hood.

You can create a test on https://jsperf.com/ to measure the performance of both approaches. Feel free to report the results back!

On jsperf, I get either that the two are the same, or that using concat is 1%-3% faster.

I don't know when anyone will need 0-3% more speed reversing a string though:)
