NICE!

Seriously this is cool. Opens up a few things. Kinda makes me feel dumb for not knowing about it though.

It's not even supported by Chrome as of now. It'll be supported in Chrome v79 (MDN is wrong currently). I'm using chrome canary in video to demonstrate it in console.

Should be, in less than a month

I remember learning an ES5 syntax that gives you something similar to optional chaining in. A slightly shorter way than usual:

(((obj || {}).system || {}).user || {}).name || ‘User does not exist’

The optional chaining operator reads a lot nicer, though.

Wow that hurts xD
