What's New in JavaScript for 2019

I'm _super_ excited for flat and flatMap. In working with multidimensional arrays, I'm always needing to use my own `flatten` function before returning my value. I love that this is getting native support.

The only thing that still blows my mind are the private fields and methods. I understand there has been plenty of debate about it, but have not followed the conversation. I really hope that syntax does not get finalized.

Kill it with fire.

Why?

Not the OP, but so much about javascript rubs me the wrong way.

1) Mandatory javascript is making the internet a hostile place. Basically every site you visit asks you to run untrusted code to view it now. What could possibly go wrong?

2) It's a hastily thrown together language that was rushed out the door by a Netscape engineer long ago, and it shows.

3) The 'ecosystem' is like swamp right now, at least to me. Frameworks and approaches change almost monthly. To me the whole thing looks like totally unstable set of immature code that I'd hesitate to build on.

This one was weird but for someone who only does Javascript it might not. # is not a comment in Javascript but is in many other languages I use which really threw me for a loop.
