// 4 Oct 2017 - add name object example.
// 14 Nov 2017 - pass `a.name, b.name` to `byName()`; rename `test` as `diff`.
// 1 Jan 2018 - made some functions more readable.

// Inspired by post at https://alistapart.com/article/what-i-talk-about-when-i-talk-about-sorting
// which covers an example of sorting by age, but does not ensure items of same age are secondarily
// sorted by name in alphabetical order.

// This snippet shows how to do that whether names are strings or objects with first and last properties.
