Add example for ES6 to README about object.entries

[ljharb]

I'm not sure how import vs require makes usage of the package any different - the README already has an example of both modular and shimmed usage.

In general, examples for feature X shouldn't rely unnecessarily on feature Y - in this case, for..of support.

That's a point, but still i had to dig into the code to understand how things are working, wouldn't use Object.entries without an ES6 syntax, but that's more a personal preference. I think the ES6 example is more clear how Object.entries is useful as some assert.deepEqual(Object.entries(obj), expected);. I never used this assert module, maybe i'm missing something out. Anyways, the example relies on this assert module, which is not needed to use Object.entries and therefore not a good and self explaining example in my opinion.

If we think about the future, ES6 will be the standard, why not give it a short example?
I'm using Object.entries only for [key, value], that was the reason i looked for this module, and maybe some others are doing this too. A self explaining example would be a good thing.

Sure, PRs welcome.

Fwiw, assert is both a nice core module and common pseudocode throughout CS and every language to denote assertions.

How do I use the 'auto.js' functionality? I don't want to add a bunch of code; that's what I'm trying to avoid by using a polyfill.

@pabrams import 'object.entries/auto' or require('object.entries/auto') in your app's entry point is sufficient.

Closing for now; happy to accept documentation PRs in the future.
